Governing statute and constitutional framework
Mexico's termination and severance regime rests on Article 123, Section A, Fraction XXII of the Constitución Política de los Estados Unidos Mexicanos and its implementing statute, the Ley Federal del Trabajo (Federal Labour Law, "LFT"). Article 123 establishes that in the event of despido injustificado (unjust dismissal), the worker has the right at the worker's election either to reinstatement in the position or to an indemnización (indemnity) equivalent to three months' salary. This constitutional election means that an employer who cannot prove just cause for dismissal faces either the obligation to rehire the employee or to pay a statutory minimum indemnity, with the worker controlling which remedy applies.
The LFT implements this framework in Articles 47–51. Article 48 LFT grants the dismissed worker the right to request, before the Autoridad Conciliadora (Conciliation Authority) or the Tribunal (Labor Court) if conciliation fails, either reinstatement in the prior role or indemnización of three months' salary calculated at the rate in effect on the payment date. If the employer fails to prove the stated cause for rescission (termination for cause) in the proceeding, the worker is entitled—regardless of which remedy was initially requested—to salarios vencidos (back pay) for the period from dismissal through judgment, capped at twelve months. If the proceeding extends beyond twelve months or the judgment remains unfulfilled at that point, Article 48 further requires the employer to pay interest on fifteen months' salary at 2 percent monthly, compounded at the moment of payment.
Article 49 LFT lists narrow exceptions to the reinstatement obligation. The employer may substitute the indemnización calculated under Article 50 for reinstatement when: (I) the worker has less than one year of service; (II) the tribunal finds, considering the circumstances, that the worker's direct and permanent contact with the employer makes normal continuation of the relationship impossible; (III) the worker holds a puesto de confianza (position of trust—a managerial or confidential role); (IV) domestic workers (trabajo del hogar); (V) temporary workers (trabajadores eventuales); or (VI) platform-digital workers (personas trabajadoras de plataformas digitales), added by the December 24, 2024 reform. In all other cases, the worker's election to demand reinstatement is enforceable by court order.
Article 50 LFT specifies the indemnización amounts when reinstatement is waived or unavailable:
- Fixed-term contracts under one year: salary for half the service period.
- Fixed-term contracts over one year: six months' salary for the first year plus twenty days' salary per each subsequent year of service.
- Indefinite-term contracts: twenty days' salary per year of service (Article 50, Fraction II, as amended December 24, 2024).
- Plus the constitutional three months' salary (Article 50, Fraction III).
- Plus back pay (salarios vencidos) and interest under Article 48, if the dismissal was unjustified and the employer lost the proceeding.
For platform-digital workers, Article 50, Fraction IV (added December 24, 2024) provides that indemnización consists of three months' salary plus twenty days' salary per year of service (computed based on time actually worked per Article 291-D LFT), plus back pay and interest under Article 48.
Article 51 LFT provides the mirror image: grounds on which a worker may terminate the relationship without liability (rescisión sin responsabilidad para el trabajador). These grounds include the employer's fraud in hiring (Fraction I), violence, harassment, or immoral acts by the employer or representatives (Fraction II), unsafe working conditions (Fraction VII), and other employer misconduct. If a worker invokes Article 51 and the employer contests and loses, the worker receives the same indemnity package as in an unjustified employer-initiated dismissal.
Article 47 LFT enumerates the employer's just-cause grounds for rescission without liability. These include worker dishonesty, repeated absences (more than three in thirty days without permission), insubordination, intoxication or drug use at work, and other serious misconduct. The employer must deliver written notice to the worker stating the specific conduct and the date(s) it occurred (Article 47, final paragraphs). Failure to provide this written notice creates a presumption that the dismissal was unjustified. The causes listed in Articles 47 and 51 are exhaustive; any termination outside those enumerated grounds is per se unjustified and triggers the Article 48/50 protections.
Mexico does not recognize at-will employment for standard employment relationships governed by Article 123(A) of the Constitution. The Constitution and LFT together create a strong presumption of job security, backed by the reinstatement right and substantial indemnity for unjustified dismissal. A foreign employer hiring in Mexico—whether through a local entity or an employer-of-record arrangement—should plan for the reality that terminating an employee without one of the enumerated statutory causes will result in either a court-ordered reinstatement or a severance package comprising the three-month constitutional indemnity, the Article 50 statutory severance (twenty days per year for indefinite contracts), and—if the case proceeds to litigation—up to twelve months' back pay plus compounded interest on fifteen months' salary.

Notice requirements for termination for cause — the *aviso de rescisión*
Article 47 LFT establishes not only the enumerated grounds for termination without employer liability but also the strict procedural requirements that an employer must satisfy to make a rescisión con causa justificada (termination for cause) effective. The statute imposes a mandatory written-notice regime, and failure to comply—regardless of whether a substantive just cause exists—creates a presumption of unjustified dismissal that shifts the burden to the employer to prove the dismissal was justified. In practice, non-compliance with the notice formalities is one of the most common reasons employers lose unfair-dismissal proceedings and are ordered to pay the full Article 48/50 severance package or reinstate the worker.
Content of the *aviso de rescisión*
The employer who dismisses a worker for cause must deliver a written notice (aviso escrito) that states clearly:
- The conduct or conducts that motivated the rescission, and
- The date or dates on which the conduct was committed.
Article 47, penultimate paragraph (as reformed November 30, 2012 and May 1, 2019) requires specificity. Generic language such as "lack of integrity" or "poor performance" is insufficient; the notice must identify the precise act (e.g., "absent without permission on March 5, 6, and 8, 2026" or "threatened a co-worker with physical violence in the warehouse on March 10, 2026 at approximately 2:00 p.m."). This requirement serves two purposes: it allows the worker to prepare a defense in any subsequent conciliation or tribunal proceeding, and it prevents post-hoc fabrication or shifting of the alleged cause.
Timing and delivery of the notice
The notice must be delivered personally to the worker in one of two ways:
- At the moment of dismissal, handed directly to the worker with the employer requesting acknowledgment of receipt (firma de recibido), or
- **Via the labor tribunal within five working days** (cinco días hábiles siguientes) if the worker refuses to accept the notice or cannot be located.
If the employer chooses the second route, Article 47 requires that the employer file the notice with the Tribunal competente (since the 2017 constitutional reform and the 2019 implementation of the new labor-justice system, this is the Tribunal Laboral in the federal or local jurisdiction, replacing the former Junta de Conciliación y Arbitraje) and provide the worker's last registered domicile so that the tribunal can effect personal service (notificación personal).
The five-working-day clock starts on the date of the dismissal. "Working days" (días hábiles) exclude Saturdays, Sundays, and the official rest days enumerated in Article 74 LFT (New Year's Day, the first Monday of February, Constitution Day, May 1, Independence Day, the third Monday of November, Revolution Day, Christmas, and electoral holidays). If the employer misses the five-day window—for example, by waiting six working days to file with the tribunal—the procedural defect alone triggers the presumption of unjustified dismissal.
Legal consequences of failure to deliver notice
Article 47, final paragraph (added November 30, 2012) states unequivocally:
> "La falta de aviso al trabajador personalmente o por conducto del Tribunal, por sí sola presumirá la separación no justificada, salvo prueba en contrario que acredite que el despido fue justificado."
Translation: The failure to give notice to the worker personally or through the tribunal will, by itself, presume the termination was unjustified, unless the employer can provide contrary evidence proving the dismissal was justified.
This is a rebuttable presumption, but it imposes a heavy burden. If the employer never delivered or filed the aviso, the labor authority (Conciliation Center or Tribunal) will begin the proceeding with the assumption that the dismissal was despido injustificado, and the employer must overcome that presumption with documentary or testimonial evidence proving both the existence of the Article 47 cause and the timeliness of the decision. In practice, tribunals are skeptical of employers who assert "we had cause but forgot to notify"—the constitutional principle of in dubio pro operario (doubt favors the worker) often resolves evidentiary ties against the employer.
Moreover, Article 47, penultimate paragraph (as reformed) provides that the statute of limitations (prescripción) for actions arising from the dismissal does not begin to run until the worker receives the notice personally. This means that if the employer dismisses a worker for cause but never delivers the aviso, the worker's right to file an unfair-dismissal claim remains open indefinitely (subject to the general two-month statute of limitations in Article 518 LFT once the worker has actual knowledge of the dismissal, but proving "actual knowledge" without formal notice is difficult for the employer).
The thirty-day outer time limit for employer action
Although Article 47 does not expressly state it in the notice paragraphs, Article 517 LFT establishes that the employer's right to invoke a cause for rescission expires thirty calendar days after the employer becomes aware of the cause. This is a separate timing requirement: the employer must both decide to dismiss within thirty days of learning of the misconduct and deliver or file the written notice either at the moment of dismissal or within five working days thereafter. If the employer waits more than thirty days after learning of the employee's three unexcused absences (for example) to issue the aviso, the cause is extinguished even if the notice formalities are perfect.
Practical implications for cross-border employers
A foreign company hiring in Mexico—whether through a local subsidiary, a branch, or an employer-of-record arrangement—must plan for this two-step formality:
- Document the cause contemporaneously. When misconduct occurs, the employer should prepare an acta administrativa (administrative record) signed by witnesses and, ideally, by the worker (though the worker's refusal to sign does not invalidate the acta). The acta establishes the date and details of the conduct.
- **Draft and deliver the aviso de rescisión within the statutory windows.** Use the documented facts to prepare a written notice that names the Article 47 fraction, describes the conduct in detail, and states the date(s). Attempt personal delivery at the moment of dismissal. If the worker refuses, file with the tribunal within five working days and keep proof of filing (the tribunal will issue a receipt and will serve the worker at the registered address).
Failure to execute these steps—even when the employer has video evidence of theft or a confession of the misconduct—will result in the dismissal being treated as unjustified, obligating the employer to pay the Article 50 indemnity (three months' salary plus twenty days per year of service for indefinite contracts, plus prima de antigüedad) and, if the case proceeds to judgment, up to twelve months' back pay under Article 48.

Collective dismissals and redundancy requirements — procedures under LFT Articles 434–439
Mexico's Federal Labour Law (Ley Federal del Trabajo, LFT) governs collective dismissals — mass layoffs or redundancies affecting all or a significant portion of a workforce — in Title Three, Chapter IX, Articles 434–439. Unlike the regime for individual dismissal, collective termination triggers a distinct set of substantive and procedural safeguards, including employer obligations to notify and obtain approval from labor authorities, and—in some cases—engage in negotiations with worker representatives.
What constitutes a 'collective dismissal' under Mexican law?
Article 434 LFT defines the scenarios in which an employer may lawfully terminate employment relationships en masse:
- The closure of a company, work center, or establishment when due to force majeure or extinction of the enterprise (Frac. I, II)
- The physical or technological bankruptcy of the enterprise (Frac. III)
- The legally declared insolvency or bankruptcy of the employer (Frac. IV)
- The reduction of the workforce or the implementation of technical changes due to a manifest and significant decrease in work or market conditions (Frac. V)
The law does not set a clear numeric threshold for what constitutes a collective dismissal (for example, "more than 10 workers" or "at least 10% of the workforce"), instead tying the determination to the facts and the scale of change—closure, significant downsizing, or technological transformation. Employers should treat any plan involving closure of an establishment or reduction by a substantial number of positions as potentially triggering the collective-dismissal rules.
Procedural and approval requirements
Articles 435–436 LFT require the employer to obtain prior approval from the Juntas de Conciliación y Arbitraje (now replaced by Centros de Conciliación and Labor Tribunals after the May 2019 labor reform) before carrying out a collective dismissal on economic grounds (technical or market-related). The process is:
- The employer submits a proposal justifying the need for collective dismissal or reduction to the Labor Tribunal, presenting evidence (e.g., financial results, market analysis).
- The Tribunal sets a hearing and notifies the affected workers and their union representatives, if any (Article 437 LFT).
- Workers may contest the necessity and scope of the reduction; the Tribunal may order expert reviews (peritaje) of the employer's financial data.
- No collective dismissal for economic or technical reasons (such as redundancy) may proceed until the Tribunal issues a final resolution authorizing the dismissals and fixing the terms of indemnification.
- For closures due to force majeure, Articles 434–436 require prompt but not pre-approval notification of the labor authority and workers.
Severance and priority
If collective dismissal is approved, workers are entitled to statutory indemnity under Article 50 LFT (twenty days' salary per year of service, three months' constitutional pay, and, in all cases, the prima de antigüedad). Article 439 LFT grants priority for re-hiring to those affected by collective redundancy for up to one year if the business resumes or normalizes.
No 'social plan' or consultation requirement
Unlike in some European jurisdictions, the LFT does not mandate the negotiation of a 'social plan' or provide specific consultation deadlines, but unionized workforces may have additional requirements under their collective agreements.
Key practical risk: Any collective redundancy without Tribunal sign-off is unlawful and exposes the employer to reinstatement orders or additional indemnities. Multinational employers must budget time for the judicial process and gather strong evidence of economic necessity before initiating collective redundancy in Mexico.
Pre-litigation conciliation requirements after dismissal — Conciliation Centers and Labor Tribunal procedure since 2019 reform
Mexico’s 2019–2022 labor justice reform introduced a mandatory pre-litigation conciliation phase for most individual and collective labor disputes, including terminations and severance claims. Title Four Bis (Arts. 684-A to 684-E) of the Ley Federal del Trabajo (LFT) now requires nearly all post-termination disputes to pass through a Centro de Conciliación (Conciliation Center) before access to the Labor Tribunal (Tribunal Laboral).
Statutory requirement and jurisdiction Article 684-A LFT establishes that any worker or employer seeking to file an individual or collective labor claim—including unjustified dismissal or severance—must first attend a conciliation session at the Centro de Conciliación. Article 685 Ter LFT lists the narrow exceptions, including occupational risk disputes where IMSS is a party, benefits from social security, domestic worker claims, constitutional rights protection cases (amparo), and disputes over union freedom and collective bargaining. All other matters require conciliation as a precondition.
Conciliation process After a termination, the party wishing to initiate a dispute (typically the employee) files a request at the appropriate Conciliation Center. Article 684-B LFT requires the Center to schedule a session within 15 calendar days. Both parties are summoned; attendance is mandatory. If either party fails to attend without just cause, Article 684-C LFT provides that the absent party may forfeit the ability to produce certain evidence or assert defenses at the next stage.
If settlement is achieved, the agreement (convenio) must be made in writing and ratified before the Center (Article 684-C II, Article 33). If no agreement is reached, or if one party refuses to participate, the Center issues a "constancia de no conciliación" (certificate of non-conciliation) per Article 684-C I. This certificate is a jurisdictional prerequisite—the Labor Tribunal may not admit a claim without it (unless the case falls within Article 685 Ter exceptions).
Employer implications and key deadlines Employers must monitor incoming conciliation notices carefully: non-attendance or delay can restrict their procedural rights per Article 684-C. Documentation (employment contract, notice of dismissal, severance calculations) should be prepared and ready for the conciliation stage. The first session must be scheduled within 15 days of the request (Article 684-B), and settlements reached at this stage, if properly ratified, have the force of res judicata and preclude later claims on the same facts (Article 33).
Cross-border employers unfamiliar with this system must align their Mexico HR compliance so that all dismissal disputes trigger timely participation in the Centro de Conciliación, as skipping this phase delays litigation and may compromise procedural defenses at the Labor Tribunal.

Formality and ratification requirements for termination settlement agreements — Article 33 LFT restriction on private waivers
Mexican labor law imposes strict formalities on settlement agreements (convenios de terminación) and waivers of statutory rights in the context of employment terminations. Article 33 of the Ley Federal del Trabajo (LFT) establishes that any waiver, settlement, or "blanket release" of labor rights is null and void unless made before the labor authority—either the relevant Conciliation Center (Centro de Conciliación) or the Labor Tribunal (Tribunal Laboral)—with full disclosure and voluntary consent by the worker.
Article 33 LFT text and requirement: Article 33 LFT expressly states:
> “Los convenios o acuerdos celebrados fuera de juicio entre el patrón y el trabajador, serán nulos si no concurren ante la autoridad del trabajo. Cualquier estipulación que implique renuncia de los derechos que otorga esta Ley, será nula, aunque se exprese en el contrato de trabajo...”
English summary: All settlement agreements or private releases between employer and employee that are not made before the labor authority are invalid. Any contractual clause or agreement—whether at hiring, during employment, or at termination—that purports to waive statutory labor rights is deemed null, even if the employee expressly agrees.
Practical implications for employers:
- No enforceable private waivers: A privately signed settlement, even with legal counsel on both sides, cannot bar future claims for statutory severance or rights under the LFT. Only agreements ratified before the Conciliation Center or Tribunal are legally effective.
- Ratification process: To effect a valid termination, the employer and worker must appear before the authority, present the settlement with an itemized breakdown (e.g., Article 50 indemnity, prima de antigüedad, unpaid wages, vacation, aguinaldo). The authority explains the rights at issue, verifies understanding and voluntariness, and ratifies the agreement. Only then does the release gain res judicata effect.
- Invalidity of “blanket waivers:” General waivers (“I hereby release all present and future claims...”) made outside the labor authority are void. The LFT protects the "irrenunciable" (non-waivable) nature of labor rights.
- Best practice: Employers should not pay any final settlement or severance until ratification before the authority. The worker's signature alone is insufficient. Failure to ratify exposes the employer to later claims and potential double-payment.
This regime applies to all standard employment relationships in Mexico and cannot be circumvented by contract. Article 33 is rigorously enforced by labor authorities and courts, and is a common source of costly errors for foreign employers.
Reinstatement remedy in unjustified dismissal: Article 48–49 framework, employer exceptions, and enforcement
Mexico’s Federal Labour Law makes reinstatement (reinstalación) the default remedy for unjustified dismissal. Article 48 LFT gives the aggrieved worker, not the employer, the right to elect either reinstatement to their former position or payment of a statutory indemnity (three months’ integrated salary, plus Article 50 severance components). This sharply distinguishes Mexican law from at-will and most European frameworks, where severance is the default and reinstatement is exceptional.
How the reinstatement right works
When a worker files a claim for unjustified dismissal, Article 48 LFT states that the worker must elect between reinstatement and indemnity. This election is made during proceedings before the Conciliation Center or, if conciliation fails, before the Labor Tribunal. If the worker opts for reinstatement and the employer cannot prove just cause (Article 47 grounds), the tribunal orders the employer to restore the worker to their original position, with all seniority and benefits intact, retroactively. The order is directly enforceable—if the employer fails to reinstate, wage liability and procedural sanctions accrue (see Article 48, final paragraphs).
Employer exceptions: When reinstatement can be refused (Article 49)
Article 49 LFT enumerates narrow exceptions where the employer may opt to pay statutory indemnity in lieu of complying with a reinstatement order. These are:
- The worker has less than one year’s service (Fraction I)
- There is close, permanent contact rendering the relationship unworkable (Fraction II — the tribunal must so find based on the facts)
- The worker holds a position of trust or confidence (trabajador de confianza) (Fraction III)
- The worker is a domestic worker (Fraction IV)
- Temporary or event-based workers (trabajadores eventuales) (Fraction V)
- Workers performing digital platform work (Fraction VI, as amended in 2024)
If one of these applies, the employer may pay the Article 50 indemnity rather than reinstate. Outside these cases, the default is the worker’s right to reinstatement (Article 49, final clause).
Enforcement mechanics and risks for employers
When the Labor Tribunal issues a reinstatement order, the employer must comply promptly or face ongoing wage liability ("back pay" under Article 48), up to 12 months. If the worker was not reinstated due to the employer’s refusal, the salary accrual continues, plus interest at 2% monthly, compounding on 15 months’ salary after 12 months (Article 48, final paragraphs). In practice, labor authorities monitor compliance closely and noncompliance can trigger further penalties or, in rare cases, coercive enforcement measures.
International employers must note: settlement with the worker (even on generous terms) is only final if ratified before the Conciliation Center or Tribunal (Article 33 LFT). Unratified settlements do not bar a later reinstatement claim.
Key takeaways:
- Reinstatement is the rule, indemnity the exception—unless the employer proves an Article 49 ground.
- Orders are strictly enforced: refusal incurs wage penalties.
- Employers commonly negotiate settlements prior to tribunal orders to control cost exposure.
Calculation of base salary for severance and indemnity: daily wage, integrated salary, statutory caps (LFT Articles 84, 89, 485, 486)
The amount owed to a worker as statutory severance or indemnity in Mexico depends on the "salary base" (salario base) used for each payment component. The Ley Federal del Trabajo (LFT) sets strict rules for how the salary must be calculated, varying according to the type of compensation (severance, seniority premium, other labor rights) and the nature of the worker's compensation (fixed salary, commissions, or mixed).
Article 84 LFT: Definition of Integrated Salary (Salario Integrado) Article 84 LFT establishes that "the salary comprises the cash payments, daily quota, bonuses, room and board, commissions, benefits in kind, and any other amount or benefit the worker receives for their work." Excluded are profit-sharing, extraordinary bonuses, and employer-provided tools. For most indemnities (three months' pay for unjustified dismissal, twenty days per year under Article 50), the calculation uses the "salario integrado" (integrated salary)—i.e., ordinary base pay plus the regular value of fixed recurring benefits (such as the mandatory Christmas bonus/aguinaldo and vacation premium), and benefits in kind where these are part of regular compensation.
Article 89 LFT: Variable Income and Averaging If the worker earns variable income (commissions, piecework, tips), Article 89 directs that the employer must calculate the average daily integrated salary over the preceding year. If service was less than a year, the average covers the entire period worked. This rule ensures that indemnity calculations reflect actual earnings, not just contract base pay.
Articles 485 and 486: Statutory Cap for Certain Indemnities While ordinary severance indemnities (three months' pay, twenty days per year) are calculated on the actual integrated salary without cap, some payments—most notably the "prima de antigüedad" (seniority premium)—are subject to a limit. Article 485 specifies the base may not be less than the minimum wage. Article 486 states: "If the worker’s salary exceeds double the minimum wage of the corresponding geographic area, for purposes of calculating the indemnity, the maximum salary to be considered shall be double the minimum wage." Thus, for the "prima de antigüedad," if the worker’s integrated salary is above this threshold, the cap applies. Despite administrative and judicial practice using the Unidad de Medida y Actualización (UMA) in place of the minimum wage following constitutional amendments, the statutory language still references the minimum wage; employers should check for updated official guidance before applying UMA in actual calculations.
Summary Table
- Three months’ indemnity (Art. 48/50): Integrated salary (no cap).
- Twenty days per year severance (Art. 50): Integrated salary (no cap).
- Prima de antigüedad (Art. 162): Integrated salary, capped at double the minimum wage (per Art. 486).
- Variable pay: Use average daily integrated salary (Art. 89) over the last year (or full period if less).
A miscalculation of the salary base is a frequent source of disputes in severance cases. Employers must document all salary elements and apply the above legal formulae rigorously.
Statute of limitations (prescripción) for unfair dismissal and severance claims under LFT Articles 518–521
Mexican labor law imposes strict deadlines for workers and employers to initiate claims arising from termination. These limitation periods (plazos de prescripción) are governed mainly by Articles 518 to 521 of the Ley Federal del Trabajo (LFT). Understanding when the clock starts and how it may be tolled or extended is essential for both employers seeking finality and workers preserving their claims for reinstatement, back pay, or severance.
Article 518 LFT: The general statute of limitations for a worker to bring a claim for unjustified dismissal and related indemnity (such as the three months' constitutional pay and Article 50 severance) is two months (dos meses) from the date the employment relationship is terminated. This also applies to claims for reinstatement or back pay. For claims seeking payment of accrued benefits (such as salaries, unpaid vacation, or bonuses), the statute of limitations is one year from when the payment was due.
Trigger for the limitation period:
- Article 47 LFT (notice of dismissal) intertwines with Articles 518–519: if the employer fails to provide the required written notice of termination (aviso de rescisión) to the worker personally or through the Labor Tribunal, the two-month period to challenge the dismissal may not begin to run. The courts and labor authorities interpret "termination" as the date the worker receives formal notice or, in its absence, acquires actual knowledge (e.g. denied entry to work, cut off from payroll). In practice, failure by the employer to give proper notice can leave a dismissal action open to challenge long after the worker was dismissed (see Article 47, penultimate paragraph and Article 519).
Conciliation Center overlay:
- Following the 2019 reform, Article 521 LFT provides that the statute of limitations is "interrupted" when a party submits a claim to a Conciliation Center seeking a certificate of non-conciliation (constancia de no conciliación). The period does not resume until the conciliation procedure concludes or is abandoned. This means that timely filing at the Centro de Conciliación preserves the worker’s rights even if more than two months elapse before the case reaches the Labor Tribunal.
Employer claims against workers:
- Article 518 LFT also sets a one-month limitation period for employers to pursue claims against workers arising from the termination (e.g., repayment of unearned advances or material debts).
No shortening by contract:
- Article 518, final paragraph, prohibits parties from setting shorter limitation periods by private agreement. Any contractual clause waiving or shortening prescripción is null and void.
Practical takeaways:
- Employers should meticulously document delivery of termination notices, ideally with dated acknowledgment, to trigger the prescriptive period.
- Workers should act promptly and use the Conciliation Center process to preserve their rights in case of dispute over the dismissal date or notice.
Severance entitlements for fixed-term contracts: Article 50 formula and triggering events
Mexico’s Federal Labour Law (Ley Federal del Trabajo, LFT) distinguishes clearly between severance and termination rules for employees hired on fixed-term (contrato por obra o tiempo determinado) contracts and those on indefinite-term contracts. Practitioners must reference Article 53 LFT for the possible ends to a fixed-term contract, and Article 50 LFT for the statutory indemnity formulas.
Triggering events — when does severance apply?
- If a fixed-term contract naturally expires (i.e., the work or time period is completed), and there is no continuation of the employment relationship, no severance is owed (Art. 53, Fraction I; Art. 39-I LFT).
- If the contract is terminated before its natural end, or if the justification provided by the employer is deemed unfounded or not proven (rescisión sin causa justificada), statutory severance applies as if it were an unjustified dismissal (Art. 53, Fraction IV).
Statutory severance formula under Article 50 LFT:
- For contracts of up to one year: the employee is entitled to compensation equivalent to the wages for half the time remaining of the contract (Art. 50, Fraction I).
- For contracts exceeding one year: compensation is at least equal to wages of six months for the first year, plus twenty days of salary for each additional year (Art. 50, Fraction I, second paragraph).
- If the worker’s employment continues for thirty days or more after the fixed term ends without explicit renewal, the relationship is presumed indefinite (Art. 39 LFT), making the employee eligible for the full Article 50 indemnity as for indefinite-term contracts.
Article 162 LFT (prima de antigüedad) also applies, adding twelve days’ salary per year of service, even for fixed-term contracts, when terminated unjustifiably (see the existing section on prima de antigüedad for cap details).
Common pitfalls:
- Employers frequently believe that project or fixed-term contracts allow for easy separation at will; Mexican law treats most premature terminations as unjustified unless clearly valid cause under Article 47 is proven.
- Attempting to use successive fixed-term contracts to avoid indefinite-status conversion typically fails under Article 39—Mexican law grants the worker indefinite status if tasks are of a permanent or continuing character, regardless of contract language.
In sum, fixed-term contracts offer no escape from statutory severance rules: early non-justified termination triggers compensation based on time served and time remaining, with additional payments if the contract exceeds one year. Practitioners should structure project or seasonal hires with clear documentation and budget accordingly for potential severance.
Protected categories and dismissal restrictions: pregnancy, union activity, and anti-discrimination grounds under the LFT
Mexico’s Federal Labour Law (Ley Federal del Trabajo, LFT) establishes heightened dismissal protections for workers in specific protected categories and for certain prohibited grounds. These protections apply in addition to the general severance regime, and dismissals violating them may be treated as null, with workers entitled to reinstatement or statutory indemnity per Article 48 LFT.
1. Pregnancy and maternity protection
Article 133(XV) LFT prohibits employers from dismissing or coercing a worker to resign due to pregnancy, a change in civil status, or care responsibilities for minor children. Articles 164–170 LFT reinforce job security during pregnancy and maternity leave, including the right to six weeks’ paid leave before and after childbirth (Article 170). Dismissals during pregnancy or maternity leave are presumed discriminatory and void unless the employer can substantiate a lawful reason completely unrelated to these grounds. If challenged, and the employer cannot disprove this connection, Article 48 LFT entitles the worker to reinstatement to the same position with accrued wages from dismissal to judgment (up to twelve months’ back pay) or, at the worker’s election if an exception applies, statutory indemnity (three months’ salary, twenty days’ salary per year, plus seniority premium, as applicable under Article 50).
2. Union activity and delegate protection
Union delegates and workers engaged in union activities receive specific protections under Articles 133(XI) and 358–364 LFT. Article 133(XI) prohibits dismissal or harm to union delegates during their commission period without just cause previously approved by the competent tribunal. Article 364 further bans employer interference with union rights. Dismissals of union delegates without this process are null; the worker is entitled to reinstatement and back pay as per Article 48 LFT. Dismissals based on union membership or lawful activities are likewise prohibited, and aggrieved workers may seek reinstatement or indemnity.
3. Prohibited discriminatory grounds
Article 133(bis) LFT and related subsections expressly prohibit dismissal on the basis of race, sex, sexual orientation, age, disability, religion, migratory status, health, or marital status. Discrimination on these grounds may render the dismissal void, with the worker entitled to remedies under Article 48 (reinstatement or indemnity, with capped back pay and related benefits). The Federal Law to Prevent and Eliminate Discrimination offers further sanctions for such acts.
Practical note: In all these scenarios, independent settlement agreements must comply with Article 33 LFT, requiring ratification before the labor authority to be valid. Attempts to resolve terminations of protected workers privately are likely to be set aside in favor of statutory remedies.

When an employment relationship ends in Mexico, the employer must pay more than the statutory severance or seniority premium: all accrued but unused statutory benefits must be settled at termination. The most material of these are:
- Proportional vacation pay (vacaciones proporcionales),
- Proportional aguinaldo (Christmas bonus), and
- Any wages or benefits accrued but unpaid to the termination date.
1. Unused vacation days (Art. 79 LFT)
Article 76 LFT grants all workers annual paid vacation. Article 79 LFT states: "If at the termination of the employment relationship the worker has not enjoyed the vacation to which they are entitled, the employer must pay the corresponding compensation." This payment is made even if the worker resigned or was dismissed for cause. The amount must reflect both the days accrued but not taken and the statutory vacation premium (Art. 80 LFT—25% over ordinary pay).
2. Proportional aguinaldo (Art. 87 LFT)
Article 87 LFT entitles every worker to an annual aguinaldo (Christmas bonus) — minimum fifteen days’ salary, payable by December 20. If employment ends before year's end, the worker is entitled to a proportional part, calculated by dividing 15 days by 365 and multiplying by days worked that year. Payment is due on termination regardless of reason.
3. Accrued wages and benefits (Arts. 98 et seq; Art. 123)
Articles 98–101 LFT require prompt payment of all wages to the separation date. Article 123 LFT protects against retention of payments due. The final paycheck must also settle any pro-rated benefits (such as statutory bonuses, overtime owed, unpaid commissions).
Practical requirement
Payment of these benefits is not optional, cannot be waived in a private agreement outside the labor authority (see Art. 33), and is cumulative with all separation indemnity. Failure to pay accrued benefits exposes the employer to litigation, fines, and payment of additional interest. The receipt should itemize each component and be formally ratified, ideally in the Conciliation Center if part of a broader settlement.
Cross-border note: This duty applies regardless of contract type, reason for termination, or worker's election of reinstatement/indemnity. Foreign employers must treat vacation/aguinaldo payout as a cost center distinct from severance itself.
Probationary period termination: rules, maximum duration, and severance exceptions under Article 39-A LFT
Mexico’s Federal Labour Law (Ley Federal del Trabajo, LFT) allows employers to establish a probationary period (periodo de prueba) for new employees, with distinct rules for dismissal and severance during this initial period. Article 39-A LFT, last reformed in April 2012, governs the maximum duration of probation and the process for termination during this time—a subject that frequently traps cross-border employers unfamiliar with Mexican law’s formalities.
Maximum duration
- Article 39-A LFT authorizes probationary periods of up to 30 days for most employments.
- For positions of trust (puestos de confianza), professional, technical, or specialized work, or for employees in managerial roles or with specialized training, probation may be extended up to 180 days (six months).
- Probationary periods must be explicitly stated in the written employment contract. If not agreed in writing, or if the maximum duration is exceeded, the employment is presumed indefinite from the outset.
Termination during probation
- Article 39-A permits the employer to terminate the employment relationship during the probationary period without triggering the standard severance obligation—but only if the employer can demonstrate that the employee does not meet the required skills or competencies for the role.
- However, the employer must document and justify the grounds for termination in accordance with Article 39-A’s requirements. A perfunctory dismissal (“probation not passed”) is insufficient. The worker is entitled to challenge the termination, and the employer carries the burden to show objective performance shortfalls unrelated to discrimination or prohibited grounds.
Procedural warning
- Article 39-A further requires that any probation dismissal be conducted with the knowledge of the union delegate (if any) and, if the employee requests, the corresponding labor authority.
- Importantly, employees dismissed during probation retain the right to payment of accrued wages, unused vacation, proportional aguinaldo, and other non-waivable benefits under Articles 79, 87, 98 et seq LFT.
No severance—but strict formalities
- If the probationary period is properly invoked—written contract, compliant duration, documented skills review—a worker dismissed for failing the probation is not entitled to statutory severance under Article 50 LFT, but the employer must be prepared to defend the process in any subsequent labor proceeding.
- Terminations must not violate protected-category restrictions (pregnancy, union activity, discrimination) or the dismissal will be deemed unjustified, triggering full severance and potentially reinstatement rights even during probation.
Practical summary for cross-border employers
- Stipulate the probation in writing, respecting the maximum durations.
- Document concrete, role-specific performance issues.
- Provide all accrued statutory benefits on exit.
- Avoid discriminatory or retaliatory grounds.
- When in doubt, involve the union delegate or seek labor authority oversight during the separation meeting.

Calculation and payment of interest on back pay (salarios vencidos) after the 12-month cap — Article 48 LFT regime for unjustified dismissal
Article 48 of the Ley Federal del Trabajo (LFT) governs the payment of "salarios vencidos" (back pay) and interest in cases of unjustified dismissal, establishing a capped and penalty-enhanced regime for delayed proceedings or employer non-payment.
Statutory 12-month cap on back pay: If a worker prevails in an unjustified dismissal claim and reinstatement does not occur, the employer must pay back pay for the period from dismissal through judgment. However, since the 2012 labor reform, Article 48 provides: “En caso de que el patrón no compruebe la causa de la rescisión, el trabajador tendrá derecho, además de los salarios devengados y no pagados, a recibir los salarios vencidos desde la fecha de despido hasta por un período máximo de doce meses…” (If the employer does not prove just cause, the worker is entitled, in addition to any accrued but unpaid salary, to receive back pay from the date of dismissal up to a maximum period of twelve months). This rule limits the employer's exposure if litigation extends beyond a year.
2% monthly interest on fifteen months’ salary after 12 months: If the judgment or payment is delayed beyond twelve months, Article 48 continues: “…transcurridos doce meses sin que se cumpla con el monto de la condena por concepto de salarios caídos, se pagarán al trabajador intereses al dos por ciento mensual, capitalizables al momento del pago, sobre el importe de quince meses de salario, independientemente del tiempo que dure el juicio o de la fecha en que se cumpla la condena…” (After twelve months without payment of the ordered back pay, the worker shall receive interest at two percent monthly, capitalized at payment, on the amount equivalent to fifteen months’ salary, regardless of the duration of the trial or the time at which judgment is satisfied).
Interest calculation mechanics:
- The statutory language requires interest to accrue at 2% per month, but not to compound monthly: the interest is capitalized once, at the moment the employer settles the full amount.
- The interest base is specifically set at fifteen months' integrated salary (not the entire elapsed period), per Article 48’s language. Judicial interpretation may vary; the statute is explicit about the 15-month base, but does not break down month-by-month allocation.
Example: If a judgment is issued 18 months after dismissal, the employer would owe:
- Back pay for 12 months;
- Plus 2% per month simple (not compounded monthly) interest, accruing for 6 months (months 13–18), on an amount equal to 15 months' salary, capitalized at the time of payment.
Procedural notes for employers:
- This regime is mandatory for unjustified dismissal findings under the LFT; the employer cannot contractually waive or avoid these statutory minimums (see Article 33 for restrictions on waivers).
- Delay in payment—whether due to litigation or employer noncompliance—triggers interest automatically after the 12-month cap.
Employers should monitor timelines carefully post-dismissal to budget for both capped back pay and, if proceedings extend past twelve months, the statutory interest amount.
Termination and severance for domestic workers (trabajadores del hogar) after the 2022 reform — Article 331 and Article 49 LFT special rules
Mexico’s 2022–2024 reforms substantially shaped the termination and severance framework for domestic workers (trabajadores del hogar), bringing their rights into closer alignment with other LFT-covered employees but retaining key exceptions and protections. The core legal regime for domestic workers at separation now appears in Articles 331 to 331 X Bis (Chapter XIII Bis) of the Ley Federal del Trabajo (LFT), together with Article 49 (Fracción IV—domestic worker exception to reinstatement), and was most recently amended on December 24, 2024 to add an additional exempt category (digital platform workers) under Article 49, Fracción VI.
Definition and scope: Article 331 LFT defines a domestic worker as one who habitually provides paid labor in a home to a household or family (including cleaning, cooking, care, or driving). The law mandates a written employment contract (Art. 331 Bis VI) and registration with IMSS (Art. 331 Bis VII).
Severance rules for unjustified dismissal:
- Where dismissal is without just cause (as defined in Article 47), a domestic worker is entitled to:
- Three months’ integrated salary (Article 50, Fracción III—by reference from Article 49, Fracción IV);
- Twenty days’ salary per year of service if on an indefinite contract (Article 50, Fracción II);
- Seniority Premium (prima de antigüedad): 12 days’ salary per year of service, capped at double the minimum wage (Article 162 II, Article 486 LFT);
- Accrued and unpaid benefits: unused vacation (Article 79), proportional aguinaldo (Art. 87), and wages due at termination (Arts. 98–101).
Procedure and employer prerogatives:
- Employers are not required to reinstate domestic workers post-dismissal: domestic work remains a statutory exception (Article 49, Fracción IV) and employers may opt to pay indemnity in lieu of reinstatement. Since December 24, 2024, this exception has been expressly extended to digital platform workers (Fracción VI).
- Written notice is obligatory for terminations for cause (Article 47, as revised by the 2019 reform)—failure to deliver notice triggers a presumption of unjustified dismissal and severance liability.
- Settlement agreements or waivers at separation must be ratified before the labor authority to be valid (Article 33, 331 Bis VII).
Mandatory social security:
- Registration with IMSS is compulsory (Article 331 Bis VII); pilot program ended May 2022. All current domestic work relationships require IMSS registration.
Important update, December 2024:
- On December 24, 2024, Article 49 was amended to add Fracción VI, making clear that persons working on digital platforms are now also excepted from the reinstatement remedy. The rule for domestic workers under Fracción IV remains unchanged but is now part of a broader category of exceptions. Practitioners should reference the current LFT text for up-to-date exception lists.
Summary: The fundamental obligations for separation—indemnity in lieu of reinstatement, full severance, and IMSS registration—remain the current standard for domestic workers post-2022/2024 reforms. Settlement and notice requirements are strict, and severance formulas are effectively harmonized with those governing other employment relationships, except for the continuing employer prerogative to pay instead of reinstate.
