Mexico’s 40-Hour Workweek Reform Clears Key Deputies’ Commission

The executive will unveil the proposal on September 1, opening the path to full congressional votes followed by state legislature approvals

Overview

  • On August 4, the Chamber of Deputies’ Constitutional Points Commission approved the amendment to cut the statutory workweek from 48 to 40 hours.
  • The government must formally present the initiative on September 1 to trigger a two-thirds vote in the Chamber of Deputies, Senate review and ratification by state legislatures before presidential signing.
  • The reform mandates a phased rollout beginning with a reduction to 46 hours in 2026 and reaching 40 hours by 2030.
  • The amendment guarantees that workers’ salaries will remain unchanged under the shorter workweek and maintains existing overtime pay rules.
  • Labor unions are demanding government support measures—such as low-interest loans for micro-entrepreneurs—while business groups warn of rising costs and potential evasion through extra hours or hourly contracts.
