Firing An Employee in Mexico: The Real Costs of Staff Termination

Firing an employee in Mexico is rarely as simple as handing over a letter of dismissal. The country’s labor laws are among the most employee-friendly in Latin America, and employers must handle terminations carefully to avoid costly disputes. For homeowners employing domestic staff, small business owners, and larger companies alike, understanding the rules is essential.

This guide breaks down the real costs, the legal framework, and the practical steps you must take when terminating staff in Mexico.

Why Termination Is Complex in Mexico

Mexico’s Federal Labor Law (Ley Federal del Trabajo, LFT) is designed to protect workers from unfair dismissal and ensure they receive adequate compensation if their employment ends. Unlike in the U.S. or Canada, where “at-will” employment often allows termination with limited severance, Mexican law presumes that any termination without proper cause is unjustified.

If an employer fails to follow the required steps, the employee can file a claim with the Federal or Local Conciliation and Arbitration Boards (now being replaced by specialized labor courts). These tribunals almost always rule in favor of the employee if the employer lacks written documentation.

The result? Severance payments can balloon into the equivalent of years of wages once penalties and continued salary accrual are factored in.

Severance Obligations (Finiquito vs. Liquidación)

When an employment relationship ends, two different payments may come into play:

• Finiquito: the settlement of accrued benefits such as unpaid wages, vacation days, vacation premium (25% of vacation pay), and proportional aguinaldo (Christmas bonus).
• Liquidación: severance pay owed when termination is initiated by the employer without just cause.

A typical liquidación package includes:

1. Three months of salary (constitutional indemnity).
2. 20 days of salary per year worked, for every year of service.
3. Pro-rated vacation, vacation premium, and aguinaldo.
4. Seniority premium: For employees with more than 15 years of service, 12 days’ pay per year worked, capped at double the daily minimum wage.

These amounts can be substantial, especially for long-term employees. For example, dismissing a gardener who has worked 18 years could cost hundreds of thousands of pesos once all benefits and premiums are included.

Importantly, all payments must be made at the time of dismissal. If not, the law treats the employee as still actively employed, and wages continue to accrue until the debt is settled.

When Severance Is Not Required

The law recognizes situations where severance is unnecessary:

• Voluntary Resignation: If an employee quits on their own, only the finiquito (accrued benefits) must be paid.
• Dismissal for Just Cause: The LFT lists specific grounds under Article 47 that allow an employer to terminate without paying full severance. These include:
  • Dishonesty, theft, or fraud.
  • Acts of violence or threats against the employer or other employees.
  • Repeated unjustified absences.
  • Disobeying reasonable instructions related to work.
  • Showing up intoxicated or under the influence of drugs.
  • Harassment or immoral conduct.

In these cases, the employer still owes accrued benefits (finiquito) but not the three months’ indemnity or the 20 days per year.

However, the burden of proof rests entirely on the employer. The misconduct must be documented, and the employee must receive written notice of dismissal at the time of termination. Ideally, the letter is signed in front of witnesses or delivered with acknowledgment. Without this paperwork, the law presumes the termination was unjustified, and full severance becomes payable.

Special Situations Worth Noting

1. Property Sales or Rental Changes
   If you sell your home or stop renting a property where staff are employed, their contracts don’t simply vanish. Unless the new owner or tenant formally assumes responsibility for the workers, the original employer must pay severance in full.
2. Employee Death or Retirement
   If a worker dies or retires, the employer must settle severance with the worker or their heirs. Families of deceased workers may pursue these claims through labor courts.
3. Unilateral Changes
   Reducing hours, cutting pay, or reassigning job duties without the employee’s agreement is considered constructive dismissal. In other words, it counts as termination and obligates the employer to pay severance.

Documentation & Contracts

The importance of written documentation cannot be overstated. A well-drafted employment contract is your best protection against future disputes. Contracts should specify:

• Employee’s name and CURP/RFC if applicable.
• Job title and description of duties.
• Salary, benefits, and payment method.
• Work schedule and location.
• Duration of contract (fixed-term, seasonal, or indefinite).

Employers must also keep proof of all payments—either bank transfer records or signed receipts. If a dispute arises, these documents demonstrate compliance with labor law and can significantly reduce liability.

Even if you employ domestic staff, such as a housekeeper, gardener, or driver, a contract is strongly recommended. Mexico has specific regulations for domestic workers, including mandatory enrollment in IMSS (social security), which adds another layer of employer obligations.

Risks of Ignoring the Law

Failure to follow proper termination procedures can be extremely costly. Employees who file claims may win:

• Back pay from the date of dismissal until final judgment. This often means months or even years of salary, depending on how long litigation takes.
• Accrued benefits not properly paid.
• Legal fees, which, while not directly charged to the employer, can motivate lawyers to pursue aggressive claims.

For example, firing a long-term employee without documentation could easily result in a claim exceeding half a million pesos once all components are tallied.

Practical Tips for Employers

1. Consult a Labor Lawyer
   While not legally required, professional advice is invaluable. Lawyers can draft contracts, prepare termination letters, and guide you through conciliation if disputes arise.
2. Always Have Witnesses
   When settling severance, ensure at least two neutral witnesses are present. Have the employee sign a receipt and termination letter acknowledging payment.
3. Pay Promptly
   Delays only increase liability. Calculate severance accurately and pay in full on the termination date.
4. Keep Records Organized
   Maintain contracts, payment receipts, and any disciplinary notices in one file. If taken to labor court, documentation is your best defense.
5. Consider Mediation First
   Mexico encourages employers and employees to resolve disputes through the Conciliation Centers before litigation. Reaching a settlement here can save time, money, and stress.

Why Many Employers Struggle

For many foreign residents employing staff in Mexico, the biggest challenge is not knowing the rules. Employers may assume that casual arrangements—paying cash weekly without contracts—offer flexibility. Unfortunately, this approach often backfires when a long-term worker is dismissed and seeks severance. The lack of documentation means the law automatically sides with the employee.

Similarly, small business owners sometimes overlook the importance of formal contracts, leaving themselves exposed to labor claims that can cripple operations.

Example Severance Calculation: Housekeeper

To illustrate how the law works in practice, let’s look at a common scenario: a part-time housekeeper employed one day per week for 10 years, earning 500 pesos per visit. We’ll assume all accrued vacation days and aguinaldo have been paid.

Step 1: Establish the Daily and Monthly Salary

Under Mexican law, severance calculations are based on daily integrated salary. For part-time employees, courts look at the actual agreed wage and frequency of work.

• Weekly pay: 500 pesos
• Since the housekeeper only works one day per week, this is treated as the weekly salary.
• Daily salary (for severance purposes): 500 pesos ÷ 1 day = 500 pesos/day
• Monthly equivalent: 500 × 4.3 weeks = ~2,150 pesos/month

This modest figure illustrates how the law applies proportionally, even to part-time arrangements.

Step 2: Three Months’ Salary

The baseline severance indemnity is three months of salary.

• 2,150 pesos × 3 = 6,450 pesos

Step 3: 20 Days per Year of Service

Next comes 20 days of pay per year worked, regardless of whether the worker was part-time.

• Daily salary: 500 pesos
• 20 days × 10 years = 200 days
• 200 × 500 = 100,000 pesos

This is by far the largest portion of the settlement, because long service multiplies quickly.

Step 4: Seniority Premium (Prima de Antigüedad)

Employees with more than 15 years receive 12 days per year worked (capped at 2× minimum wage). In this case, the housekeeper has 10 years, so no seniority premium applies yet.

Step 5: Total Severance

Adding it all up:

• Three months’ salary: 6,450 pesos
• 20 days per year × 10 years: 100,000 pesos
• Seniority premium: 0
• Total: 106,450 pesos

Why the Number Is So High

This example surprises many employers. Paying 500 pesos a week may not seem like much, but because the law multiplies the daily wage × years of service × 20 days, long-term employees accumulate significant severance rights.

In fact, it’s not uncommon for domestic workers—housekeepers, gardeners, or drivers employed for a decade or more—to be entitled to six-figure payouts at termination.

Key Takeaway

Even for part-time staff, severance obligations can be substantial. Employers should:

• Keep written contracts clarifying the schedule and pay structure.
• Budget ahead for the possibility of termination.
• Seek mediation before disputes escalate.

The cost of compliance may feel heavy, but failing to pay exposes employers to ongoing salary accrual and labor claims that could be even more expensive.

In Conclusion

Terminating staff in Mexico is not impossible, but it requires planning, documentation, and respect for the country’s labor laws. The real cost of dismissal extends far beyond wages. It includes severance, benefits, legal risks, and the potential for years of back pay if procedures are mishandled.

For employers, whether individuals employing domestic workers or companies managing larger teams, the key takeaways are clear:

• Always use written contracts.
• Document performance issues.
• Pay severance promptly and in full.
• Seek legal advice when in doubt.

Handled correctly, firing an employee in Mexico can be a straightforward process. Handled poorly, it can become one of the most expensive mistakes you’ll ever make.
