Mexico Sets Phased Shift to a 40-Hour Workweek Starting in 2026

Officials say the gradual schedule and new enforcement tools are meant to safeguard pay and allow businesses time to adjust.

Overview

  • The reform takes effect on May 1, 2026, with the first cut to weekly hours arriving on January 1, 2027, and subsequent two-hour reductions each year until reaching 40 hours in 2030.
  • Labor authorities state that wages and benefits will not be reduced as hours come down under the new framework.
  • The Labor Ministry plans to issue secondary regulations in the first quarter of 2026 to detail overtime calculations, penalties for noncompliance, and potential incentives.
  • Employers will be required to use an official electronic registry to track working time and verify compliance with ordinary and overtime limits.
  • Government estimates indicate about 13.4 million workers will be directly affected, with significant impact in manufacturing, retail, hospitality and food services, and transport and warehousing.
