Introduction to the 40-Hour Workweek Reform in Mexico

The reduction of the workweek to 40 hours is advancing as a priority reform, with a gradual timeline that presents operational, economic, and productivity challenges. This proposal is not merely an international trend adopted by countries like Colombia and Chile but has become a significant agenda for both the current federal government and a substantial portion of the opposition in Mexico.

Historical Context and Previous Attempts

The idea of reducing the workweek to 40 hours is not new or exclusive to the current administration. The previous government also kept this topic in the public eye, though progress was slower due to persistent disagreements among business, labor, and government sectors, especially regarding economic, operational, and productivity implications.

Formal Announcement and Stakeholder Involvement

The formal announcement was made during the 2025 Labor Day commemoration when the Mexican government revealed its decision to present a gradual reduction initiative for the weekly workweek to 40 hours, starting from 2026. As part of this strategy, workshops were held involving representatives from the business sector, unions, workers, authorities, and academia to build a consensus-based labor reform proposal.

Government Perspective and Objectives

The reform aims to address workers’ historical demands without compromising productivity, and it is believed that redistributing work hours will help revalue employment and promote a better balance between work and personal life.

Implementation Timeline

According to the proposed reform, the transition process would unfold as follows:

  • 2026 – Implementation and transition period
  • 2027 – 46 hours
  • 2028 – 44 hours
  • 2029 – 42 hours
  • 2030 – 40 hours

The ordinary workweek will be 40 hours, ensuring at least one day of rest. This design diverges from previous proposals that aimed to achieve reduction through the addition of a weekly rest day, opting instead for a direct decrease in working hours.

Key Considerations: Overtime Pay and Adjustments

An essential aspect of the reform is the management of overtime work. The draft allows for no more than 12 hours of overtime per week, distributed across up to four hours daily for no more than four days. This introduces a distinct scheme for handling overtime hours.

Furthermore, once the constitutional modification is approved, the Federal Congress will have 90 days to make necessary adjustments to the Federal Labor Law.

Political Landscape and Business Preparation

The reform is likely to advance without significant obstacles, given the official party’s legislative majority and the executive branch’s political support. The immediate challenge for the business sector will be to anticipate and design strategies to mitigate the impact, such as restructuring shifts, operational adjustments, formulating new internal policies, and possibly amending internal work regulations and individual contracts.

While the reform aims to benefit workers, its economic consequences must be carefully considered, as improper implementation could ultimately harm those it intends to protect, particularly in a context of inflationary pressure and rising costs of goods and services.
