Mexico's labor law creates compliance risk from day one
Mexico's Federal Labor Law (LFT) is a civil law system built around strong employee protections. The burden of proof in wage, overtime, and termination disputes rests with the employer, not the worker. That single fact changes how you need to approach every hire.
Oyster's in-house legal specialists have operational knowledge of LFT requirements so your hires are protected from the first contract signature.
Why most terminations in Mexico require months of severance pay
Your Head of Engineering in Guadalajara isn't working out. You plan to let them go and move on. Here's what actually happens next.
In Mexico, poor performance and redundancy are not recognized as "just cause" under Article 47 of the LFT. Nearly every involuntary termination is treated as "without cause," triggering a mandatory severance package: three months' integrated salary plus 20 days' salary per year of service, plus accrued vacation, aguinaldo, and vacation premium. That payment is due on the day termination documents are signed in person.
The employee must physically attend a signing meeting and leave a fingerprint on the documents. If they refuse, the employer has five days to file with a labor court or the termination is void. Oyster coordinates this process through its payroll provider IPS, which has signing offices across Mexico City, Guadalajara, Monterrey, Puebla, and Querétaro, with partner offices in more remote states.
Contractor misclassification in Mexico carries criminal consequences
If your company dictates how, when, or where a worker performs their tasks, regardless of what the contract says, Mexican law considers them an employee. This is the subordination test, and it is the default lens labor authorities use.
Misclassification triggers retroactive liability for all IMSS contributions, AFORE deposits, aguinaldo, profit-sharing, and full statutory severance going back to the first day of engagement. In fraud cases, criminal liability applies. Using contractors in Mexico is considered high-risk unless the worker is genuinely autonomous. An EOR eliminates this exposure entirely by placing workers on a compliant employment contract from day one.
Mexico's 40-hour workweek reform changes your employer obligations
On March 3, 2026, Mexico enacted a constitutional reform reducing the maximum workweek from 48 hours to 40 hours. This applies to all employees in Mexico, including those employed through an EOR.
If your team member currently works a 48-hour week under their contract, that contract must be updated. Overtime thresholds, premium pay calculations, and shift classifications all shift with this reform. Oyster monitors regulatory changes like this and updates employment agreements proactively, so you are not caught reviewing Mexican constitutional reforms while trying to close a product sprint.
What Oyster's Mexico EOR covers on your behalf
Oyster operates as the legal employer in Mexico through OYSTER HR MEXICO (RFC: OHM230629CT0), registered in Mexico City. You get compliant employment without entity setup, and Oyster is the only B Corp-certified EOR, so beyond compliance, you are working with a partner whose employment practices are externally audited for fairness.
Setting up a Mexican entity takes six months longer than using an EOR
Back to your Guadalajara engineer. Setting up a Mexican entity means appointing a legal representative, registering with the SAT, obtaining a Registro Patronal with IMSS, opening local bank accounts, and navigating state-level requirements. The clock starts at three to six months before your first payslip runs.
An EOR has all of that infrastructure already in place. You submit a hire request; Oyster registers the employee with IMSS within five business days of their start date (a legal requirement under Mexican Social Security Law), issues a bilingual Spanish/English employment agreement, and runs their first semi-monthly payroll on the 15th or last day of the month. The operational question is whether you can afford to wait six months to prove that.
How Oyster onboards your Mexican employee in 48 hours
After you submit a hire, Oyster generates a compliant employment agreement in Spanish, coordinates right-to-work verification, and registers the employee with IMSS through its payroll provider IPS. Oyster supports Mexican nationals and permanent residents. Temporary residency with separate work permits requires case-by-case review via the Oyster RTW team.
AFORE and INFONAVIT contributions route automatically. Employees access their CFDI-stamped digital payslips directly in the Oyster platform. No copying data between systems. No chasing paper. When software is not enough, like during termination signing or visa questions, Oyster's in-house specialists step in directly. (That last part matters more than most EOR comparison pages will admit.)
How your intellectual property is protected under a Mexico EOR
Under Article 163 of the LFT, when an employee is hired to conduct research, development, or process improvement, inventions created as a result of that employment belong to the employer. Oyster's employment agreements include IP assignment clauses, confidentiality obligations covering business strategy, customer data, pricing, and technical know-how, and non-disclosure provisions that survive termination.
Non-compete clauses are generally unenforceable in Mexico because of constitutional right-to-work protections, but confidentiality and non-solicitation provisions are enforceable when clearly scoped. Oyster's legal templates are reviewed for Mexico-specific enforceability.
Mexico employment terms your EOR manages by law
The default and most common contract type in Mexico is the indefinite-term (permanent) contract. Fixed-term contracts are only valid for specific, demonstrable needs and automatically convert to permanent if overextended. Oyster's employment agreements are legal-reviewed for Mexico and include all mandatory elements under Article 25 of the LFT, with no client customization required for standard hires.
What a compliant Mexican employment agreement must include
Article 25 of the LFT requires every written employment contract to include the employee's CURP and RFC, type of employment relationship, job duties, place of work, and working hours. It must also specify salary with payment frequency, duration if not indefinite, and signed authorization from both parties.
Advanced electronic signatures are acceptable for the initial employment agreement, but termination documents require wet signatures and fingerprints in person. Contracts cannot include clauses that waive statutory minimums (minimum wage, severance, IMSS enrollment, paid leave), so any such clause is legally void. Oyster generates compliant templates for Mexico and maintains them as law changes.
Mexico probation periods vary by role complexity and cap at 180 days
Probation periods in Mexico depend on role complexity, not salary. General operational or administrative roles carry a maximum of 30 days. Specialized technical roles, like IT technicians, engineers, lab analysts, can extend up to 90 days. Specialized professional roles requiring university-level education (lawyers, accountants, HR specialists) and managerial roles can run up to 180 days.
Probation cannot be extended beyond the legal maximum or applied to someone who already performed the same role at the company. During probation, the employee has full IMSS enrollment, salary, and accrued benefits. Termination during probation for unsatisfactory performance requires no severance, but a business restructuring reason during probation is still treated as unjustified and triggers full severance liability.
Mandatory benefits and compensation Oyster administers in Mexico
Mexico has one of the more complex statutory benefit structures in Latin America. Oyster's flat EOR fee covers all statutory benefit administration including IMSS registration, AFORE routing, payslip stamping through the SAT's CFDI system, and NOM compliance coordination through its vendor partners. Transparent pricing, with no hidden fees, no termination charges on top of what Mexican law requires.
The full list of statutory benefits every Mexican employer must provide
Every employer in Mexico must provide:
- IMSS enrollment covering healthcare, disability, maternity, and childcare services
- AFORE retirement fund contributions
- INFONAVIT housing fund contributions (5% of salary)
- Aguinaldo of at least 15 days' salary, paid by December 20 annually
- Profit-sharing (PTU) of 10% of pre-tax profits, paid by May 30
- 12 days of paid vacation after year one, increasing with tenure
- Prima Vacacional (vacation premium) of at least 25% of regular salary
- 8 federally mandated public holidays
Competitive employers also offer supplemental private health insurance (Oyster offers Allianz Global Health Insurance as this benefit) and meal vouchers (Vales de Despensa), which are culturally standard and expected. Total employer cost typically runs 30–35% above gross salary depending on role risk classification and employee location.
Mexico payroll taxes and employer contributions by the numbers
See pricing on Oyster's EOR service, or book a demo for a quote. On top of the EOR fee, statutory employer contributions include IMSS components (employer contributes approximately 2% of salary to the retirement fund, 3.15% to the lay-off and old-age account, plus variable health and workplace risk rates), INFONAVIT at 5% of salary, and AFORE contributions.
Payroll runs semi-monthly, on the 15th and the last day of the month. Salaries must be quoted gross; ISR (income tax) is withheld and remitted to SAT by the EOR. Mexico has two minimum wage zones: MXN $315.04/day for the general zone and MXN $440.87/day for the Northern Border Free Zone. Oyster ensures the correct zone rate applies based on employee location.
Remote work law compliance for your Mexican team
Mexico's telework regulations under Articles 330-A to 330-K of the LFT apply when an employee performs more than 40% of their work remotely. NOM-037-STPS-2023 came into force December 5, 2023. Oyster partners with Lockton to administer NOM-035 psychosocial risk surveys and NOM-037 home office compliance, obligations that self-managed EOR setups and most competitors do not operationalize.
NOM-037 and NOM-035: what your remote Mexican hire triggers
If your Mexico employee works from home more than 40% of the time, Mexico's telework law requires a written telework agreement specifying working hours, deliverables, and right-to-disconnect terms. The employer must provide or fund ergonomic equipment, cover proportional internet and electricity costs, and conduct a home office safety risk assessment with the employee's written consent.
Oyster mandates a minimum remote work allowance of MXN $400/month for all team members to support these costs. NOM-035 separately requires employers to identify, analyze, and prevent psychosocial risk factors, like excessive workloads, harassment exposure, lack of autonomy, and conduct surveys, evaluate results, and implement prevention policies. Failure to comply risks fines exceeding 5,000 times the UMA value from the Ministry of Labor (STPS). Oyster manages both requirements through its vendor partner Lockton.
Why Oyster cares for your Mexican team better than competitors
Oyster is the only B Corp-certified EOR, and employs in-house Mexican specialists, not contracted local providers managing compliance at arm's length. Mexico terminations require in-person document signing with fingerprint verification, a process that demands established local infrastructure, not just a software dashboard.
What EOR providers won't tell you about Mexican terminations
Most EOR platforms present termination as a button you click. In Mexico, it is a logistics operation. The employee must physically sign the finiquito and termination agreement at an IPS office, with their fingerprint on each page. Oyster's payroll provider has signing offices in Mexico City, Guadalajara, Monterrey, Puebla, and Querétaro, with partner offices covering Mérida, Tijuana, Chihuahua, Cancún, and other states.
If an employee refuses to sign, Oyster files the petition with a competent labor court within five days. The final payment, including all severance calculations, is processed on the day of signing. Self-service EOR platforms that do not operate this infrastructure leave the burden of coordinating this process on you. Oyster handles it end to end, with calculations provided within 24 hours of request under its payroll SLA. Providers without in-house Mexico legal support and established payroll partnerships cannot reliably execute this.
Transparent pricing, no termination fees, B Corp accountability
EOR pricing for Mexico should have no asterisks. Oyster's flat pricing covers employment agreement generation, IMSS registration, CFDI-stamped payslip issuance, benefit administration, ongoing compliance monitoring, and human support when it matters. No termination fees on top of what Mexican law requires. No hidden markups on statutory contributions.
Other providers charge separately for legal consultations, termination management, or country-specific compliance reviews. Oyster's model is the same in Mexico as everywhere else: one transparent fee, human support included. As a B Corp, Oyster's employment practices, fair pay, ethical sourcing, employee rights, are externally verified. That matters when you are building a team in Mexico and your company's reputation extends to how those people are employed.
