Terminating an employee in Mexico is a process governed by strict statutory rules under the Federal Labor Law (Ley Federal del Trabajo, or LFT). Mexico doesn’t permit termination without cause in the same way many other jurisdictions do, and the financial consequences of getting it wrong are significant. If you employ workers in Mexico, understanding the legal framework before you act is essential.
The core principle: termination without cause triggers full severance
Mexico’s LFT doesn’t allow employers to dismiss employees without a legally recognised cause (causa justificada) without owing substantial severance. If you terminate an employee without just cause, you’re liable for a full severance package known as liquidación. The law is structured to protect workers, and labor tribunals in Mexico consistently interpret disputes in favour of employees when documentation is weak or absent.
This means the most important thing you can do before initiating any dismissal is assess whether you have a documented, legally valid cause, and whether your records can support it.
Justified causes for termination
Under Article 47 of the LFT, there are specific circumstances that allow an employer to terminate an employee without triggering the full severance obligation. These include dishonesty or violence at work, serious misconduct toward the employer or colleagues, deliberately damaging company property, disclosing confidential business information, providing false credentials during the hiring process, and unjustified absences of more than three times within any 30-day period without permission. A positive drug or alcohol test may also constitute just cause where the role makes sobriety a safety or performance requirement.
The 30-day notice rule for just cause
Even when just cause exists, the right to invoke it isn’t open-ended. You must deliver written notice of the justified termination within 30 days of becoming aware of the cause. If you miss that window, the right to terminate for just cause is forfeited and any dismissal will be treated as unjustified by a tribunal.
Severance obligations when there’s no just cause
When a termination is unjustified or lacks adequate documentation, the employer must pay a full severance package (liquidación completa). The components are as follows:
| Component | Amount |
|---|---|
| Constitutional indemnification (indemnización constitucional) | 3 months’ salary |
| Seniority premium addition (prima de antigüedad adicional) | 20 days of salary per year of service |
| Seniority premium (prima de antigüedad) | 12 days of salary per year of service, capped at twice the minimum daily wage per day |
| Proportional aguinaldo (Christmas bonus) | Accrued portion of annual bonus |
| Accrued unused vacation days | Proportional to time worked in the year |
| Vacation bonus (prima vacacional) | Proportional to accrued vacation |
| Notice period payment | 12 days of salary if notice wasn’t given |
Note that the minimum wage cap applies on a per-day basis to both the prima de antigüedad adicional and the prima de antigüedad. The three main components (constitutional indemnification, seniority addition, and seniority premium) together make up the full liquidación. The proportional benefits are owed regardless of whether the termination is justified or not.
Notice periods
Mexico’s LFT doesn’t establish a statutory notice period. Severance replaces the notice obligation. In practice, employers can choose to give 30 days’ advance notice or make a payment in lieu equivalent to 12 days of salary. Either approach is acceptable, but it’s important to document whichever route you take.
Probationary periods
Mexico allows for probationary arrangements with modified severance obligations during the trial phase. For general roles, the probationary period can last up to 30 days. For management, director-level, or highly technical roles, it can extend to 180 days.
During probation, you can terminate without paying the full liquidación. You’re still required to pay proportional benefits that have accrued during employment, including the proportional aguinaldo and any accrued vacation entitlement.
Mutual separation agreements
Many employers in Mexico use a mutual agreement (convenio de liquidación) to end the employment relationship by consent. This approach can be faster and less adversarial than a contested dismissal, but it needs to be handled correctly to be legally binding.
Ratification before a conciliation authority
A mutual separation agreement must be ratified before a labor conciliation authority, either CEJUST (Centro de Justicia Laboral) or the IMSS. Ratification is what makes the agreement enforceable and prevents the employee from bringing future labor claims. Without ratification, a signed agreement may not protect you if the employee later contests the terms.
The ratification process also triggers the requirement to deregister the employee from IMSS as part of the formal close-out.
The termination process step by step
Getting the process right procedurally matters as much as getting the legal basis right. Here’s the sequence to follow:
- Document the cause. If termination is for just cause, gather written evidence before taking any action. This includes attendance records, written warnings, incident reports, and any relevant correspondence.
- Deliver written termination notice. Issue the employee a carta de rescisión (termination letter) that specifies the cause and the date of termination. For unjustified dismissals, issue a finiquito (settlement letter) detailing the severance calculation.
- Calculate and pay all outstanding amounts. This includes outstanding wages, proportional aguinaldo, accrued vacation days and vacation bonus, and severance if applicable. All amounts must be paid promptly.
- Issue final CFDI payroll receipts. Mexican law requires that all payroll payments, including final payments and severance, be covered by a digital fiscal receipt (Comprobante Fiscal Digital por Internet). Failing to issue these creates tax and compliance exposure.
- Deregister from IMSS. You must deregister the employee from the Instituto Mexicano del Seguro Social (IMSS) within five business days of the termination date.
- Ratify mutual agreements. If you’re using a convenio de liquidación, schedule the ratification before CEJUST or IMSS before the employee’s last day or immediately after.
Employee rights at the labor tribunal
If an employee believes their termination was unjustified, they can file a claim at the labor tribunal (TEFCA, the Tribunal Federal de Conciliación y Arbitraje). Following the 2019 labor reforms, disputes are now handled by Federal Labor Courts (Juzgados Laborales Federales), which replaced the older conciliation boards.
At the tribunal, the employee can claim either reinstatement (reinstalación) to their former role or the full severance package. Employers should be prepared for the fact that labor courts are worker-friendly and that the burden of proving just cause generally falls on the employer.
At-risk areas for foreign employers
Several patterns consistently create liability for employers unfamiliar with Mexican labor law.
Poor documentation is the most common and costly mistake. Poorly documented dismissals are almost always treated as unjustified by labor tribunals, regardless of what the employer believed the cause to be. Written warnings, attendance logs, and performance records are your primary protection.
Discrimination-based terminations carry additional penalties beyond the standard liquidación. Terminating an employee on the basis of pregnancy, union membership, or disability is treated as a serious violation and can trigger punitive remedies on top of standard severance.
Collective dismissals involving larger numbers of employees may trigger additional consultation requirements under the LFT. If you’re planning a restructuring that affects multiple employees, seek local legal advice before proceeding.
IMSS deregistration delays can create ongoing social security obligations after employment ends. The five-business-day window is a hard deadline, not a guideline.
Using an Employer of Record in mexico
For foreign companies that don’t have a legal entity in Mexico, an Employer of Record (EOR) can manage the full employment lifecycle on your behalf, including compliant offboarding. An EOR takes on the legal employer responsibilities, handles IMSS registration and deregistration, issues CFDI payroll receipts, and ensures severance calculations comply with the LFT.
If you’re working with independent workers rather than employees, contractors in Mexico are subject to different rules, and misclassification is a significant risk. Structuring the engagement correctly from the outset avoids severance liability entirely.
