Overview of the 40-Hour Workweek Reform in Mexico

Mexico is set to implement a 40-hour workweek, with the transition beginning in 2026. The Secretaría del Trabajo y Previsión Social (STPS) is actively negotiating the reform’s details with labor unions, business associations, and consulting firms to ensure a gradual and flexible transition.

Key Individual: Claudia Sheinbaum

Claudia Sheinbaum, the President of Mexico City, has been instrumental in advocating for this reform. In November, she announced that the STPS will present a proposal for the 40-hour workweek to the Chamber of Deputies.

Current Status and Potential Changes

Approximately 30 million people in Mexico work more than 40 hours per week, accounting for 73% of subordinated workers. The STPS is working on a reform that would allow for a gradual and flexible transition to the 40-hour workweek.

  • Potential Changes:
    • Expanding the limit for overtime hours
    • Regulating special work schedules in the Federal Labor Law (LFT)
  • Consensus Points:
    • 100% deductibility of benefits

These changes aim to provide employers with flexibility to mitigate any negative impacts from reduced working hours, particularly in industries operating 24/7 or with atypical work arrangements.

Negotiation Progress and Timeline

Although negotiations have made progress, sources indicate that little has been accomplished so far. The STPS will hold further meetings to finalize the transition scheme and accompanying measures.

Tentatively, the gradual reduction of the workweek is expected to commence on May 1, 2026. This date holds significance as it coincides with Labor Day and marks one year since President Claudia Sheinbaum reaffirmed her commitment to the 40-hour workweek.

Legislative Interest and Next Steps

The Chamber of Deputies has shown strong interest in reducing the workweek, with 16 proposed bills aiming to decrease working hours. The Chamber of Deputies will be the originating body for this reform.

Once the proposal from the Presidency of the Republic arrives, the Comisión de Trabajo y Previsión Social, led by Diputada Maiella Gómez Maldonado, will begin analyzing it for a dictamen. The Senate, under Senadora Geovanna Bañuelos’ leadership, has also recognized the importance of this reform.
