On February 10, 2026, the united commissions of Constitutional Issues, Labor and Social Welfare, and Legislative Studies in Mexico approved a significant constitutional reform aimed at reducing the weekly work hours for employees from 48 to 40. This proposed change was initially presented by President Claudia Sheinbaum in December 2025 and seeks to amend Article 123, Section A, of the Mexican Constitution. The reform is designed to be implemented gradually between 2026 and 2030, reflecting a shift towards a more favorable work-life balance for Mexican workers.

As the proposal moves to the full Senate for discussion, it faces potential opposition from various political factions, which could affect its passage. The discussions in the Senate are crucial, as they will determine how the proposed changes can be legislated and the speed at which they can be realized. Advocates for the reform argue that it is an important step in modernizing labor laws and improving the quality of life for many employees in Mexico.

The implications of this reform could be significant for the Mexican economy and workforce. A reduced work week may lead to improved productivity, lower unemployment, and enhanced well-being for workers, aligning Mexico more closely with labor practices in other developed countries. However, the path forward will depend on the Senate's deliberations and the ability to reconcile differing viewpoints among lawmakers.
