Mexico’s 40-Hour Week Plan Details Gradual Rollout Starting 2027 in Draft Sent to Senate

Officials describe a phased shift pending congressional approval, with rest periods and overtime pay preserved.

Overview

  • The reform is not yet law and has not been published in the Diario Oficial; it remains under congressional debate.
  • The draft envisions entry into force on May 1, 2026, with two-hour annual reductions beginning January 1, 2027, toward a 40-hour limit discussed publicly for completion by 2030.
  • Federal authorities say meal breaks, rest periods and existing daily caps will not be cut, and salaries and benefits are not to be reduced.
  • Overtime remains recognized by law, and the draft proposes expanding the weekly overtime cap from 9 to 12 hours, setting a limit of four triple‑pay hours per week, and requiring electronic time records subject to STPS oversight.
  • Analysts note some workers who rely on frequent overtime could see fewer extra hours as employers reorganize shifts during a negotiated, gradual implementation.
