⚡ Quick answer
In Mexico, employment is governed by the Federal Labor Law (LFT) and there is no at-will employment. A written contract isn’t optional in practice — without one, an indefinite-term relationship is presumed against the employer. Employers must provide mandatory benefits (aguinaldo of 15 days’ salary, paid vacation, a 25% vacation premium, and PTU profit sharing), enrol staff in IMSS and INFONAVIT, and pay statutory severance on unjustified dismissal. In the UAE, contracts are also mandatory and registered, salaries run through WPS, and there is no personal income tax.
Whether you’re signing your first hire in Mexico City or setting up a Dubai entity to employ a regional team, understanding employment contracts in Mexico is the starting point for getting hiring, benefits and severance right. This guide covers the Mexican framework end-to-end — the written-contract rule, contract types, mandatory terms, probation, statutory benefits, severance, and the post-2021 outsourcing regime — then bridges into UAE hiring, where payroll, WPS and GPSSA compliance replace the Mexican rulebook entirely.
What is an employment contract in Mexico?
An employment contract in Mexico (contrato individual de trabajo) is the agreement governing the working relationship, set within the Federal Labor Law (Ley Federal del Trabajo, LFT) and Article 123 of the Constitution. Mexican labour law is strongly pro-employee: rights are irreducible minimums that a contract cannot waive, and there is no at-will employment.
The relationship is documented through a formal written contract rather than a light offer letter. Critically, the employment relationship exists in law from the moment work begins, regardless of paperwork — so the written contract mostly serves to protect the employer by recording the agreed terms, contract type and conditions. Alongside the contract, employers must register the worker with IMSS (social security) and contribute to the INFONAVIT housing fund and the retirement savings system.
Because employee rights are fixed by statute and enforced by labour courts, the scope for creative drafting is narrow and the cost of getting it wrong is high. This is closer to the UAE model than to common-law systems, in that a mandatory written contract governs the relationship; the difference is that the UAE contract is standardised and government-registered, with a single clean set of federal entitlements rather than Mexico’s layered benefits and profit-sharing obligations.
Is a written employment contract required in Mexico?
In practice, yes — a written employment contract is effectively required in Mexico, because the consequences of not having one fall entirely on the employer. Where there is no written agreement, the LFT presumes an indefinite-term relationship and treats the missing document as the employer’s failure.
A written contract is essential to establish, at minimum:
| What the contract fixes | Why it matters |
|---|---|
| Contract type | Rebuts the default indefinite-term presumption |
| Job and workplace | Defines duties and location |
| Salary and benefits | Records agreed pay above the statutory floor |
| Probation / training terms | Only valid if in writing |
| Working hours | Sets the shift and overtime baseline |
The absence of a written contract never removes the employee’s rights — it simply strips the employer of the ability to prove the agreed terms and makes an indefinite relationship the default. For a foreign employer, papering the contract correctly is the first line of defence, a discipline the UAE shares: there, the registered contract must be in place before the work permit and WPS payroll can operate.
What types of employment contract exist in Mexico?
Mexico recognises several contract types, but the indefinite-term contract is the default, and fixed or specialised forms are only valid where the law specifically allows them.
| Type | When it can be used |
|---|---|
| Indefinite-term | The default; no end date |
| Fixed-term (specific work/time) | Only where the nature of the work justifies it |
| Seasonal | Recurring seasonal work |
| Initial training | To assess suitability; capped duration |
| Probation (periodo a prueba) | Short trial period at the start |
You cannot simply choose a fixed-term contract to avoid permanency: it is only lawful when the work is genuinely temporary or project-based, and misusing it can convert the relationship to indefinite. Initial-training and probation arrangements are also time-limited and must be in writing [VERIFY current durations]. The UAE, by contrast, uses renewable fixed-term contracts under Federal Decree-Law No. 33 of 2021 as standard, without Mexico’s strict restrictions on when a temporary contract may be used.

What must an employment contract in Mexico include?
The LFT sets out mandatory content for every written employment contract. Omitting these terms weakens the employer’s position if a dispute reaches the labour courts.
| Mandatory term | Why it matters |
|---|---|
| Parties’ details | Identifies employer and employee |
| Contract type & duration | Indefinite, fixed, seasonal or training |
| Services to be provided | Defines the role as precisely as possible |
| Place of work | Fixes the workplace |
| Working day / shift | Length and type of workday |
| Salary, form & date of payment | Amount and how/when it is paid |
| Rest days, holidays, vacation | Statutory time-off entitlements |
| Training & other conditions | Any additional agreed terms |
Contracts must reflect the statutory benefits and cannot contract below them. Because those benefits — aguinaldo, vacation, vacation premium, profit sharing and social security — are extensive, the drafting burden is real, and many international groups prefer to consolidate a regional team in a simpler jurisdiction such as the UAE and let a local partner handle payroll, accounting and tax under one clear statute.
How do probation periods work in Mexico?
Probation in Mexico (periodo a prueba) is short, capped and must be in writing — it is not an at-will window. It was introduced in the 2012 labour reform and is tied to the type of role.
| Role | Maximum probation |
|---|---|
| General employees | Up to 30 days |
| Management / technical / professional | Up to 180 days |
| Initial training contracts | Up to 3 months (6 for senior roles) |
Even during probation, the employee earns full salary and benefits, and to end the relationship the employer must show — with input from the workplace joint training-and-productivity commission — that the worker did not meet the requirements of the role [VERIFY current rules]. A single probation period is allowed per worker. This disciplined approach mirrors the UAE, where probation can run up to six months under the Labour Law but termination still follows a defined process rather than free dismissal.
What mandatory benefits must employers provide in Mexico?
Mexican employers must provide a substantial package of statutory benefits (prestaciones) on top of salary. These are legal minimums, not negotiable perks.
| Benefit | Statutory minimum |
|---|---|
| Aguinaldo (year-end bonus) | ≥ 15 days’ salary, paid by 20 December [VERIFY] |
| Paid vacation | 12 days in year one, rising +2/yr to 20 (2023 reform) [VERIFY] |
| Vacation premium (prima vacacional) | ≥ 25% of salary for vacation days |
| Profit sharing (PTU) | 10% of pre-tax profit, capped since 2021 [VERIFY] |
| IMSS social security | Employer + employee contributions |
| INFONAVIT housing fund | Employer ~5% of salary [VERIFY] |
Two are especially distinctive. The aguinaldo is a mandatory year-end bonus of at least 15 days’ pay, due before 20 December. And PTU requires companies to distribute 10% of their annual pre-tax profits to employees, with the 2021 outsourcing reform capping each worker’s PTU at the higher of three months’ salary or the average of the last three years [VERIFY current cap]. The 2023 “Vacaciones Dignas” reform also doubled first-year vacation to 12 days. None of these exist in the UAE, where the only end-of-employment entitlement is end-of-service gratuity and there is no mandatory profit sharing or year-end bonus.
How does termination and severance work in Mexico?
Termination in Mexico turns on whether there is a justified cause (causa justificada) listed in the LFT. Dismissal for justified cause, proven through due process, carries no indemnity. A dismissal without justified cause is an unjustified dismissal and is expensive.
Statutory severance for an unjustified dismissal generally combines several elements. Here is an illustrative example for an employee on MXN 30,000/month with 5 years’ service (figures schematic — confirm against current law):
| Component | Formula | Illustrative |
|---|---|---|
| Constitutional indemnity | 3 months’ salary | MXN 90,000 |
| Service indemnity | 20 days’ salary × years | ~MXN 100,000 |
| Seniority premium | 12 days’ wages × years (wage-capped) | MXN — [VERIFY cap] |
| Accrued benefits | Pro-rata aguinaldo, vacation, premium | Additional |
The employee can instead demand reinstatement with back pay, and back wages can accrue while a case runs (subject to statutory limits). The seniority premium (prima de antigüedad) is 12 days’ wages per year of service, with the daily wage capped at twice the minimum wage [VERIFY]. Contrast this with the UAE, where termination follows Federal Decree-Law No. 33 of 2021 and the payout is end-of-service gratuity based on basic salary and tenure — a cleaner and more predictable calculation than Mexico’s multi-part indemnity with reinstatement risk.
Outsourcing and the REPSE reform: can you use an EOR in Mexico?
Mexico’s 2021 outsourcing reform fundamentally changed how foreign companies can engage staff. It banned the subcontracting of a company’s core (preponderant) activities — you can no longer simply have a third party employ the workers who do your main business.
⚠️ The REPSE trap for foreign employers
Only specialised services that are not part of the client’s core business may be outsourced, and the provider must be registered in the REPSE (Registro de Prestadoras de Servicios Especializados) registry. Using an unregistered provider, or outsourcing core activities, exposes both companies to significant fines, denial of tax deductions and joint liability [VERIFY current penalties]. This is why many foreign businesses employ Mexican staff through their own registered entity rather than a simple “employer of record” arrangement.
The practical effect is that “just use an EOR” is far more complicated in Mexico than in many countries. Setting up and running a compliant local entity — with correct IMSS registration and payroll — is often the cleaner route. The UAE is the opposite: a foreign group can incorporate a mainland or free-zone entity quickly and have a local partner run payroll and WPS, with no outsourcing-registration regime to navigate. Our company incorporation team handles the entity side end-to-end.
Are non-compete and confidentiality clauses enforceable in Mexico?
Confidentiality clauses are enforceable in Mexico. Post-termination non-compete clauses generally are not, because the Constitution protects every person’s freedom to work.
| Clause type | Mexico position |
|---|---|
| Confidentiality / trade secrets | Enforceable |
| IP assignment | Enforceable |
| Post-termination non-compete | Generally unenforceable (freedom to work) |
| Non-solicitation | Uncertain; drafted narrowly at best |
Article 5 of the Mexican Constitution guarantees the freedom to engage in any lawful profession or trade, and a clause that stops a former employee from working in their field is typically treated as an unlawful restraint [VERIFY current position]. Employers instead protect themselves through confidentiality and trade-secret provisions and through the Federal Law for the Protection of Industrial Property. As with every country in this series, restrictive covenants are jurisdiction-specific and cannot be copied from a US, Canadian or offshore template — and the same applies when drafting UAE contracts.
Mexico vs UAE: how does hiring compare?
Mexico and the UAE both mandate written contracts and reject at-will dismissal, but Mexico layers on profit sharing, a year-end bonus, heavy social-security costs and an outsourcing-registration regime. The UAE is registered-contract, WPS-driven and free of personal income tax.
| Feature | 🇲🇽 Mexico | 🇦🇪 UAE |
|---|---|---|
| At-will employment | No — severance on dismissal | No — contract-based |
| Written contract required | Effectively yes (presumption otherwise) | Yes — mandatory & registered |
| Personal income tax on salary | Yes — ISR (progressive) | None |
| Mandatory profit sharing (PTU) | Yes — 10% of profit | No |
| Year-end bonus (aguinaldo) | Yes — ≥ 15 days | No (gratuity instead) |
| Payroll mechanism | Bank transfer + IMSS/INFONAVIT filings | Wage Protection System (WPS) |
| Social contributions | IMSS + INFONAVIT + retirement | GPSSA — UAE/GCC nationals only |
| Outsourcing / EOR | Restricted (REPSE registration) | No such regime |
| Governing law | Federal Labor Law (LFT) | UAE Labour Law (FDL 33/2021) |
❌ Expanding to the UAE without local support
- • Mexican-style contract with irrelevant benefit clauses
- • Salaries paid outside WPS — non-compliant
- • Missed GPSSA registration for UAE/GCC nationals
- • No Corporate Tax or VAT registration for the new entity
- • End-of-service gratuity mis-accrued or ignored
Result: fines, work-permit blocks, rework
✅ Hiring in the UAE with Fastlane
- ✓ Compliant, registered UAE employment contracts
- ✓ WPS-registered salary transfers, on time
- ✓ GPSSA set up for eligible nationals
- ✓ Corporate Tax & VAT registration handled
- ✓ Gratuity and payroll run monthly, audit-ready
Result: compliant from day one
Hiring in the UAE: WPS, GPSSA and contracts explained
When you hire in the UAE, the framework is far simpler than Mexico’s: a mandatory registered employment contract, salary payment through WPS, and GPSSA pension contributions for UAE and GCC nationals only. There is no personal income tax, so the employee’s gross salary is what they keep, subject only to any agreed deductions.
Private-sector employment is governed by Federal Decree-Law No. 33 of 2021 and its executive regulations. Contracts are fixed-term (renewable), probation can run up to six months, and on termination employees are entitled to end-of-service gratuity calculated on basic salary and length of service [VERIFY exact accrual bands]. There is no mandatory profit sharing, no aguinaldo and no outsourcing-registration regime.
The Wage Protection System (WPS), monitored by MoHRE, requires employers to pay staff electronically through approved channels so wages are traceable and timely. Late or non-payment can trigger fines and suspension of new work permits [VERIFY current penalties]. For UAE and GCC nationals, employers must also register with the General Pension and Social Security Authority (GPSSA) and remit pension contributions — expat staff are outside GPSSA. Getting these moving parts right from the first payroll run is exactly what Fastlane’s payroll and WPS service is built for.
What does compliant UAE payroll cost?
Running compliant UAE payroll has two cost layers: the employee cost (salary, gratuity accrual, and GPSSA for nationals) and the compliance cost (payroll processing, WPS, and the tax registrations your new entity needs). Unlike Mexico, there is no PTU, no aguinaldo, no IMSS/INFONAVIT employer burden and no income tax to withhold on salaries.
Here’s a simple worked example for one expat employee on a mainland setup:
| Item | Monthly (AED) | Notes |
|---|---|---|
| Gross salary | 15,000 | Paid in full — no income tax deducted |
| Personal income tax | 0 | No personal income tax in the UAE |
| Social security / profit sharing | 0 | No IMSS/INFONAVIT/PTU equivalent |
| GPSSA (expat) | 0 | Applies to UAE/GCC nationals only |
| End-of-service gratuity accrual | ~1,000 | Accrued on basic salary [VERIFY bands] |
On the compliance side, Fastlane sets up and runs payroll and WPS as a managed service, and handles the tax registrations that come with employing people through a UAE entity:
| Service | Fastlane price |
|---|---|
| Corporate Tax registration | From AED 199 |
| Corporate Tax filing | From AED 249 |
| VAT registration | AED 199 |
| VAT filing | From AED 149 |
| Payroll + WPS setup | Managed service |
For context, a UAE entity only enters Corporate Tax at 9% on profits above AED 375,000, and registers for VAT once taxable supplies pass AED 375,000 (mandatory) or AED 187,500 (voluntary). Salaries themselves are never taxed — the cost of employing in the UAE is genuinely the salary plus gratuity plus light compliance, which is what makes it attractive for regional headcount versus a high-benefit jurisdiction like Mexico.
Common cross-border hiring mistakes to avoid
Companies moving between Mexico and the UAE make the same avoidable errors. Most come from assuming one country’s rules travel with the employee. The costly ones:
- Copy-pasting a Mexican contract into the UAE. PTU, aguinaldo and IMSS clauses have no meaning under UAE law; the contract must follow Federal Decree-Law No. 33 of 2021 and be registered.
- Paying UAE salaries outside WPS. Even one off-system payment can breach WPS and put future work permits at risk.
- Missing GPSSA for national hires. Employers must register and contribute for UAE/GCC nationals — a step Mexico-based teams routinely overlook.
- Ignoring end-of-service gratuity. UAE gratuity accrues from day one and must be funded — it is not the same as Mexican severance.
- Assuming an EOR works the same way. Mexico’s REPSE outsourcing rules are strict; the UAE has no equivalent, but you still need a compliant local entity and payroll.
- Forgetting the entity’s own tax duties. Employing through a UAE company brings Corporate Tax and possibly VAT obligations that must be registered on time.
The clean way to avoid all six is to let a local, FTA-registered team stand up your UAE employment, payroll and tax framework from the outset. That’s precisely the remit of Fastlane’s payroll services and company incorporation support.
