If your Czech company plans to employ a worker in Mexico or negotiate employment-law matters with a Mexican company, you will encounter surprisingly different legal requirements. Mexican labour law is significantly more employee-protective and includes a range of obligations that differ fundamentally from Czech regulation. In this article, you will learn what the most common risks are, which pitfalls to watch out for, and how to avoid costly mistakes.

Quick summary

  • The principle of employment stability – Mexico applies a strong principle of employment stability. An employer may dismiss an employee without the obligation to pay high severance only on narrowly defined statutory grounds. Otherwise, termination is very costly.
  • Mandatory written contracts and specific content – A Mexican employment contract must include far more mandatory particulars than a Czech one (precise place of work, benefits, training, designation of beneficiaries in the event of death). If there is no written contract, the burden of proof lies with the employer and the employee’s statements are deemed true.
  • Mandatory benefits and social security – In Mexico, there are mandatory benefits (Aguinaldo, vacation, profit sharing – PTU) that cannot be contractually excluded or reduced. Registration with IMSS (social security) is mandatory from day one. Errors in contributions are strictly penalized.
  • Probationary period and fixed-term contracts – The probationary period lasts a maximum of 30 days (or 180 days for management and specialists) and cannot be extended. Fixed-term contracts may be concluded only in statutorily justified cases (replacement for another employee, temporary nature of the work); otherwise, they are automatically deemed indefinite-term contracts.

Key features of employment law in Mexico

Employment law is one of the riskiest legal areas for foreign companies that are not prepared for local specifics. Czech entrepreneurs often draw on their domestic experience and assume that employment principles are similar worldwide. The reality is different.

Mexican employment law (Ley Federal del Trabajo – LFT) is built on a completely different philosophy than Czech legislation. While in the Czech Republic contractual freedom within statutory limits plays a role and there are clear notice periods, Mexico places an extreme emphasis on the employee’s social protection, with any doubt interpreted in the employee’s favor.

The lawyers at ARROWS, a Prague-based law firm, handle employment-law matters in Mexico on a regular basis thanks to the broader ARROWS International network. We know that Czech companies are often surprised not only by the content of the regulations, but also by their enforcement, the role of trade unions, and the severity of fines. Let’s clarify what a Czech company should pay particular attention to.

The principle of employment stability in Mexico

In the Czech Republic, an employer may give an employee notice for the reasons set out in Section 52 of the Labour Code, with the employment ending upon expiry of a two-month notice period. In Mexico, there is no notice period in the Czech sense.

Mexican employment law is based on the principle that an employee has the right to stable employment. An employer may dismiss an employee without having to pay so-called constitutional severance only for reasons expressly stipulated by law (LFT) (e.g., theft, violence, falsification of documents, more than 3 unexcused absences in a month).

In practice, this means that if a Czech company wants to dismiss a Mexican employee due to redundancy or dissatisfaction with performance (that does not reach the threshold of serious misconduct), it must pay the employee high compensation (so-called indemnización).

If the employer fails to prove the reason in court, the employee is entitled to reinstatement or substantial financial compensation. This includes 3 months’ salary, 20 days for each year of service if reinstatement is refused, seniority premiums, and other related entitlements.

Mandatory written form of the employment contract and the burden of proof

In the Czech Republic, the written form of an employment contract is required by law, but its absence does not automatically mean the employment relationship is invalid if work has already commenced. In Mexico, the absence of a written contract has fatal procedural consequences for the employer. Under Mexican law, the employer bears responsibility for the non-existence of the contract.

This means that if there is no written contract, all of the employee’s statements regarding salary level, working hours, length of employment, or benefits are deemed true unless the employer proves otherwise (which is not possible without documentation). The absence of a written contract therefore puts the employer in a position where it can practically never win an employment dispute.

Mandatory elements of a Mexican employment contract

A Czech employment contract must include the type of work, place of work, and start date. A Mexican contract (Article 25 LFT) requires much more. It must include: name, nationality, age, gender, marital status, unique identification code (CURP), federal tax identification number (RFC), and the addresses of the employee and the employer.

The contract must also include a precise designation of the workplace(s), the length and schedule of working hours, the amount of salary and the day and place of payment, information on training, designation of authorized persons in the event of the employee’s death, and other particulars.

A Czech company that concludes a contract without these details risks administrative fines and losing any potential dispute. It is so complex that we strongly recommend foreign companies have their contracts prepared by lawyers who understand local specifics and current legislative changes (e.g., teleworking regulation).

The lawyers at ARROWS, a Prague-based law firm, prepare employment contracts with all of these requirements in mind.

Differences in working hours and overtime

In the Czech Republic, standard working hours are 40 hours per week. In Mexico, the law distinguishes three types of shifts with different limits: day shift (max. 48 hours per week), night shift (max. 42 hours per week), and mixed shift (max. 45 hours per week). An employer in Mexico cannot require an employee to work overtime without proper pay.

Overtime in Mexico is paid as follows: the first 9 hours of overtime per week are paid at double the normal hourly rate (100% premium). Overtime exceeding 9 hours per week is paid at triple rate (200% premium). Exceeding overtime limits (more than 3 hours per day, 3 times per week) is additionally sanctionable.

Aguinaldo and the mandatory Christmas bonus

One of the biggest surprises for Czech companies is Aguinaldo. In Mexico, the employer must provide each employee with an annual bonus of at least 15 days’ wages, which must be paid no later than 20 December. This right cannot be contractually excluded.

Although legislative debates are ongoing about increasing this amount to 30 days, as of 2026 the constitutionally guaranteed minimum remains 15 days; however, many collective bargaining agreements or company policies set higher amounts. If an employee did not work the entire calendar year, they are entitled to a pro-rata portion of the Aguinaldo. Failure to pay this bonus leads to direct sanctions from the labour inspectorate.

Vacation and vacation premium

In the Czech Republic, an employee is entitled to at least 4 weeks of vacation. In Mexico, the vacation system underwent a major reform in 2023 (“Vacation with dignity”). Currently, an employee is entitled to at least 12 working days of paid vacation after the first year of service.

This entitlement increases by 2 days for each additional year up to 20 days (after 5 years), and then increases by 2 days every 5 years. In addition, employees are entitled to the so-called Prima Vacacional—a premium of at least 25% of the salary attributable to the vacation days. Vacation cannot be paid out instead of being taken (except upon termination of employment).

Social security (IMSS) and housing (INFONAVIT)

Whereas in the Czech Republic insurance contributions are paid to the state by both employer and employee, in Mexico IMSS (Instituto Mexicano del Seguro Social) plays a key role. Registering an employee with IMSS is mandatory no later than the working day preceding the start date, or at the latest on the start date itself. The employer pays contributions for healthcare, occupational risks, disability, old age, and maternity.

The amount of contributions (the so-called Cuotas Obrero-Patronales) depends on the risk level of the work and the amount of wages. In addition, the employer is required to contribute 5% of gross wages to the INFONAVIT housing fund. Errors in registration or understating wages for insurance purposes are punished by high fines and additional assessments of contributions with penalties (so-called Capitales Constitutivos), which can be devastating for a company.

Employees’ profit sharing (PTU)

A specific feature of Mexican law is mandatory employee profit sharing (Participación de los Trabajadores en las Utilidades – PTU). Companies must distribute 10% of their taxable profit among employees. Payment must usually be made by the end of May of the following year. This obligation does not apply to newly established companies in their first year of operation and to certain specific non-profit organisations.

Švarcsystem and misclassification of cooperation

In 2021, Mexico introduced a strict reform against outsourcing and disguised employment. If a Czech company hires a worker in Mexico on an invoice (“honorarios”) as an independent contractor, but that worker follows instructions, has fixed working hours, and is economically dependent, this constitutes a hidden employment relationship.

Sanctions for such conduct are extreme. In addition to retroactive payment of taxes, social security, and benefits, there is a risk of high administrative fines, which may reach millions of CZK (up to MXN 5 million in the most serious cases of breaching the outsourcing ban), and in extreme cases such conduct may be classified as tax fraud.

Insufficient social security and employee registration

Failing to register an employee with IMSS, or registering them with a lower-than-actual wage, is very risky in Mexico. If a workplace accident occurs involving an unregistered employee, IMSS will provide care, but will then recover all costs from the employer (surgery, rehabilitation, lifetime annuity) in the form of a so-called “Capital Constitutivo”. These amounts can easily exceed millions of CZK for a single accident.

Probationary period and its limits

In the Czech Republic, a probationary period of 3 months may be agreed (6 months for managerial roles). In Mexico, the probationary period is max. 30 days for standard positions and up to 180 days for managerial, technical, or highly specialised positions. The probationary period cannot be extended.

Importantly, termination during the probationary period in Mexico is not entirely “without stating a reason”. The employer should be able to demonstrate that the employee did not prove the necessary abilities for the position, for which the opinion of the mixed commission for productivity and training serves (a formal requirement that is often overlooked).

Fixed-term contracts

A fixed-term contract is permitted in Mexico only in cases specified by law. These are mainly situations where the nature of the work requires it (e.g., a temporary project, seasonal work), or where an employee is substituting for another employee (e.g., illness, maternity leave).

If the contract lacks a precise justification for the temporary nature, or if the reason does not exist (it is a permanent position), the contract is automatically considered an indefinite-term contract, regardless of what is written in it.

Working hours, breaks, and safety

An employee is entitled to a rest and meal break of at least 30 minutes during a shift, and in practice an hour is often provided. If the employee cannot leave the workplace during the break, this time counts as working time.

Mexico places strong emphasis on occupational safety (NOM standards). Every employer with a certain number of employees must establish a joint commission for safety and hygiene. Failure to comply with occupational safety standards may lead to a shutdown of operations by the labour inspectorate.

Grounds for dismissal without severance (Justified Dismissal)

Dismissal without the obligation to pay severance is possible only on the grounds listed in Article 47 of the LFT. These include, for example, submitting false documents regarding qualifications (only within 30 days of starting employment), violence, threats, or insults in the workplace. This also includes intentional damage to the employer’s property, more than 3 unexcused absences within a 30-day period, or reporting to work under the influence of alcohol or drugs.

The employer must deliver to the employee a written notice describing the conduct and the date on which it occurred. If the employee refuses to accept it, the notice must be delivered through the court/tribunal.

Financial consequences of wrongful dismissal

If the employer has no legal ground or fails to prove it, this constitutes “wrongful dismissal” (Despido Injustificado). The employee is entitled to constitutional compensation equal to 3 months’ salary and a seniority premium (12 days’ wages for each year of service). They are also entitled to payment of outstanding benefits and further sanctions in the event of litigation.

Foreign workers in Mexico

Under Mexican law, at least 90% of employees in an undertaking must be of Mexican nationality (for technical and professional roles, if Mexicans are not available, an exception may be granted temporarily). This rule does not apply to directors, administrators, and general managers.

To employ a Czech national in Mexico, a work visa and residence permit are required. The employer must be registered with the immigration authority (INM) and be authorised to issue job offers (Constancia de Inscripción del Empleador). Foreign nationals have the same rights in employment relationships as Mexicans.

Checklist for a Czech company

If your Czech company is planning to hire an employee in Mexico, it should go through several key steps. First, decide on the legal form (branch, subsidiary, EOR), because direct employment by a Czech company without a local entity is complicated. Do not use a translated Czech contract; have a localised version prepared instead.

Obtain a tax number (RFC) and register with IMSS. Expect costs to be approximately 25–30% higher than the gross salary. Have an Internal Work Rules document (Reglamento Interior de Trabajo) prepared, which must be registered with the labour authority.

International context in ARROWS International countries

Attorneys from ARROWS, a Prague-based law firm, handle employment law matters in many countries. The main difference between the Czech Republic and Mexico lies in the flexibility of termination. While in the Czech Republic the process is formal and tied to notice periods, in Mexico the process is primarily financial (immediate termination bought out by severance). The Mexican system is also more formalistic in terms of documentation—what is not signed on paper is as if it never happened.

Frequently asked questions on Mexican employment law

1. Can I dismiss an employee due to “redundancy”?
Mexican law does not recognise “redundancy” as a ground for termination in the same way as Czech law. If you eliminate a position, you must pay the employee full compensation (3 months + 20 days/year + seniority premium), unless you agree otherwise.

2. What happens if I do not pay an employee Aguinaldo?
The employee has one year to assert the claim in court. The labour inspectorate may impose a fine of 50 to 5,000 times the UMA unit (which can amount to up to hundreds of thousands of CZK) for each affected employee.

3. Is it possible to agree on an all-in salary including benefits?
In principle, not for statutory minimum entitlements. Salary must be separated from benefits such as Aguinaldo. It is not possible to claim that a “high salary already includes the Christmas bonus” unless this is explicitly and lawfully addressed (which is problematic for statutory entitlements).

The decision to hire an employee in Mexico requires respect for local rules, which are strongly protective of employees. Forget Czech practices and prepare for an environment where paper documentation and social protection are king. Mistakes in structuring employment relationships can be fatally expensive for a Czech company.
