2. 核心規定 (Core Provisions)

2.1 Maternity & Nursing Leave (Licencia de maternidad y lactancia) 🟢

• 法條: Constitución Art. 123-A-V; LFT Art. 164, 170
• 內容:
  • Maternity leave duration: Total of 12 weeks (84 days) — divided into:
    • 6 weeks (42 days) before the expected due date (descanso prenatal)
    • 6 weeks (42 days) after delivery (descanso postnatal)
  • Transfer of prenatal leave (LFT Art. 170 §II):
    • The employee may request to transfer up to 4 weeks of prenatal leave to the postnatal period
    • Requires a medical certificate confirming the employee is fit to continue working
    • This allows a 2+10 week split (2 weeks prenatal, 10 weeks postnatal)
  • Extension for complications:
    • If the employee is unable to work due to pregnancy or childbirth complications, additional leave is granted as medically certified
    • If the child is born with a disability or requires hospitalization, postnatal leave may be extended by up to 8 additional weeks (LFT Art. 170 §II Bis)
  • Maternity pay: The employee receives 100% of her salary during maternity leave, paid through the Instituto Mexicano del Seguro Social (IMSS) as an incapacity benefit (subsidio de incapacidad por maternidad)
    • The IMSS benefit equals the employee's average daily salary from the last 12 months
    • If the employee is not registered with IMSS (employer non-compliance), the employer must pay the full salary directly
  • Adoption leave (LFT Art. 170 §IV Bis):
    • Female employees who adopt a child are entitled to 6 weeks of postnatal leave from the date the child is received
  • Nursing breaks (LFT Art. 170 §IV):
    • During the first 6 months after childbirth, the employee is entitled to two 30-minute breaks per day (total 1 hour) for nursing
    • These breaks are paid working time
    • The employer must provide a clean, private, and adequate space (lactario) for nursing or expressing milk
    • The nursing break period may be extended beyond 6 months if medically justified
  • Paternity leave (LFT Art. 132 §XXVII Bis):
    • Male employees are entitled to 5 working days of paid leave upon the birth of a child or the granting of an adoption

• 置信度: 🟢Constitutional and LFT provisions well-established

2.2 Pregnancy Dismissal Protection (Protección contra despido por embarazo) 🟢

• 法條: LFT Art. 170 §VI; Constitución Art. 123-A-V
• 內容:
  • Prohibition of dismissal during pregnancy and maternity leave:
    • The employer may not dismiss a pregnant employee or an employee on maternity leave except for serious cause (causa grave) as defined in the LFT
    • Even in cases of serious cause, the employer must follow the full disciplinary procedure and the dismissal is subject to strict judicial review
  • Job guarantee upon return (LFT Art. 170 §VI):
    • The employee has the right to return to her position upon completing maternity leave
    • The position must be the same or equivalent with the same salary and working conditions
  • Protection extends to the entire pregnancy period:
    • From the confirmation of pregnancy through the end of maternity leave
    • There is no formal "post-maternity" stability period in the LFT (unlike Brazil), but courts have held that dismissal shortly after return may constitute pregnancy discrimination
  • Pregnancy as protected category in discrimination law:
    • LFT Art. 3 and Art. 133 §I explicitly prohibit conditioning employment on pregnancy tests or certificates of non-pregnancy
    • Requesting a pregnancy test as a condition of hiring is an administrative violation
    • The 2012 LFT reform added explicit language prohibiting pregnancy-related discrimination
  • Constitutional protection: Art. 123-A-V of the Constitution enshrines the right of pregnant and nursing employees to maintain their employment
  • Constructive dismissal: If the employer creates intolerable conditions to force a pregnant employee to resign, courts may treat the resignation as an unlawful dismissal 🟡
• 罰則:
  • Wrongful dismissal: the employee is entitled to reinstatement plus back-pay (salarios caídos) from the date of dismissal to the date of reinstatement, or, at the employee's election, severance compensation (3 months salary + 20 days salary per year of service)
  • Requiring a pregnancy test: administrative fine (multa) and potential criminal liability under anti-discrimination statutes

• 置信度: 🟢Prohibitions well-established in the LFT; specific NOM references for weight limits need cross-check

2.5 Gender Discrimination & Harassment (Discriminación de género y acoso) 🟢

• 法條: LFT Art. 2, 3, 3 Bis, 47, 51, 133; NOM-035-STPS-2018; Ley General de Acceso de las Mujeres a una Vida Libre de Violencia

    • Mandatory for all employers in Mexico (scope varies by size):
      • 1–15 employees: basic compliance (anti-violence policy, identification of exposed workers)
      • 16–50 employees: above + identification and analysis of psychosocial risk factors
      • 50+ employees: above + comprehensive assessment and preventive action plan
    • Psychosocial risk factors include: excessive workload, lack of control over work, workplace violence, harassment, and interference with work-life balance
    • Required actions:

    • Employer-initiated (Art. 47): The employer may dismiss an employee for acts of harassment or violence against co-workers (just cause / causa de rescisión)
    • Employee-initiated (Art. 51): The employee may resign and claim constructive dismissal compensation if the employer, employer's family members, or representatives engage in harassment, violence, or sexual harassment against the employee; or if the employer fails to take measures to prevent such conduct

  • Criminal liability: Sexual harassment (hostigamiento sexual) is a criminal offense under the Código Penal Federal (Art. 259 Bis) — imprisonment of up to 2 years; if the aggressor is in a position of authority, the penalty increases
• 置信度: 🟢LFT provisions and NOM-035 requirements well-documented; criminal law provisions verified

3. 立法理由與實務見解 (Rationale & Practice)

• 立法背景: 🟢

  • Mexico's special protection framework has evolved significantly in the last decade:
    • 2012 LFT reform: added definitions of harassment and hostigamiento sexual; prohibited pregnancy tests
    • 2018: NOM-035 issued — first mandatory standard addressing psychosocial risks in the workplace
    • 2019: Major labor justice reform (separate from special protection, but affecting enforcement mechanisms)
    • 2022: Minimum working age raised from 14 to 15
  • Mexico ratified ILO Convention 138 (Minimum Age) and Convention 182 (Worst Forms of Child Labour)
  • USMCA/T-MEC labor provisions include commitments to combat forced labor and protect workers' rights, indirectly strengthening enforcement of special protections

• 重要判決/函釋: 🟡

  • The Supreme Court (SCJN) has issued tesis confirming:
    • Pregnancy tests as a condition of employment are unconstitutional and violate the right to privacy and non-discrimination
    • Dismissal of a pregnant employee creates a presumption of discriminatory motive; the employer bears the burden of proving the dismissal was unrelated to pregnancy
  • STPS has published guías (guides) for NOM-035 compliance, including model questionnaires and implementation toolkits

• 實務灰色地帶: 🟠

  • NOM-035 enforcement: While the standard is mandatory, enforcement has been uneven. STPS inspections prioritize high-risk industries (manufacturing, mining); service-sector and small business compliance is less monitored
  • Pregnancy discrimination in practice: Despite the legal prohibition on pregnancy tests, some employers (particularly in maquiladoras and small businesses) continue to request them informally. CONAPRED (National Council for the Prevention of Discrimination) receives complaints but enforcement is slow
  • Informal economy: Approximately 55% of Mexico's workforce operates in the informal economy, where maternity leave, anti-discrimination protections, and minor employment restrictions are largely unenforced
  • NOM-035 questionnaire burden: Employers with 50+ employees must administer detailed questionnaires on psychosocial risk factors — compliance requires significant HR resources and organizational commitment

• 近年修法趨勢: 🟡

  • Ongoing proposals to extend maternity leave beyond 12 weeks (various bills in Congress; no consensus as of early 2026)
  • Proposals to extend paternity leave from 5 to 20 days (not yet enacted)
  • STPS has increased NOM-035 inspection activity since 2022
  • Growing international attention to forced labor in Mexican agriculture and manufacturing (linked to USMCA enforcement mechanisms)

4. 雇主合規重點 (Employer Compliance Hotspots)

• 🔴Never require pregnancy tests: Requesting a pregnancy test as a hiring condition or during employment is a violation of LFT Art. 133 and constitutional rights. This includes indirect requirements (e.g., requiring "general health certificates" that include pregnancy testing).
• 🟢Grant full 12-week maternity leave: 6 weeks prenatal + 6 weeks postnatal; allow transfer of up to 4 weeks from prenatal to postnatal with medical certificate. Ensure IMSS registration is current for benefit payment.
• 🟢Provide lactation space and nursing breaks: Two 30-minute breaks/day for 6 months; provide a clean, private lactario.
• 🟢Verify age and authorization for minor employees: Confirm age with official documents; obtain and retain parental/guardian authorization; register with IMSS.
• 🟢Comply with NOM-035-STPS-2018: Implement psychosocial risk prevention policy; apply questionnaires for 16+ employee companies; develop action plans for identified risks. Maintain compliance records for STPS inspections.
• 🟡Establish anti-harassment protocols: Include clear definitions, reporting channels, investigation procedures, and disciplinary consequences in the reglamento interior de trabajo (internal work regulations).
• 🟡Ensure minor employees' school attendance: Working hours must accommodate school schedules; if the minor has not completed basic education, facilitate attendance.
• 🟡Limit minor working hours: Maximum 6 hours/day for all workers 15–17; no night work (10 PM–6 AM); no overtime under any circumstances.

5. 與其他轄區的關聯 (Cross-References)

• 與 vietnam：🔶 差異 — Vietnam provides 6 months maternity leave vs. Mexico's 12 weeks. Both set minimum age at 15. Vietnam has stronger post-maternity employment protection (guaranteed to child age 12 months); Mexico's protection ends at the conclusion of maternity leave.
• 與 brazil：🔷 相似 — Both prohibit pregnancy tests as hiring conditions. Brazil's estabilidade gestante (5 months post-birth stability) is stronger than Mexico's protection. Brazil's Lei 14.457/2022 (CIPA harassment prevention) is more prescriptive than NOM-035 regarding harassment specifically.
• 與 usa-federal：🔶 差異 — The U.S. FMLA provides 12 weeks unpaid leave; Mexico provides 12 weeks paid (through IMSS). U.S. has no federal mandatory nursing break space requirement beyond PUMP Act (2022); Mexico requires a dedicated lactario.
• 與 china：🔶 差異 — China's maternity leave varies by province (typically 98–158+ days); Mexico is uniform at 84 days. China's minimum working age (16) is higher than Mexico's (15).

6. 風險警示 (Risk Flags)

• 🔴高風險 — Pregnancy test prohibition: CONAPRED and the Federal Labor Courts actively sanction employers who condition hiring on pregnancy testing. This includes indirect methods (requiring "medical certificates" that include pregnancy results). Fines and reputational damage are substantial.
• 🔴高風險 — Child labor in supply chains: International scrutiny (USMCA, U.S. Department of Labor) of Mexican supply chains for child labor has intensified. Companies in agriculture, manufacturing, and maquiladora sectors face reputational and trade-access risk if minor employment violations are found.
• 🟡中等風險 — NOM-035 non-compliance: STPS inspections are increasing. Companies that have not implemented the psychosocial risk assessment and prevention program face fines and potential extraordinary inspections. The questionnaire requirement for 50+ employee companies is particularly burdensome but non-negotiable.
• 🟡中等風險 — Maternity discrimination litigation: Courts increasingly apply a presumption that dismissal during or shortly after pregnancy is discriminatory, shifting the burden to the employer to prove otherwise.
• 🟡中等風險 — Informal economy exposure: Multinational companies with operations in Mexico should ensure that outsourced or subcontracted workers receive full special protections, particularly after the 2021 subcontracting reform (reforma de subcontratación) eliminated most outsourcing arrangements.
