Overview
- Mexico's Chamber of Deputies, which approved the implementing reform Wednesday with 441 votes, sent it to the Executive for publication and set entry into force on May 1, 2026.
- The law creates a preparation window through December 2026, with the first cut to 46 hours on January 1, 2027, and a phased path to 40 hours and a 12-hour weekly overtime cap by 2030.
- Employers must use an electronic time clock to record start and end times, with rules and exceptions to be issued by the Labor Ministry in 2026 and fines of 29,327 to 586,550 pesos for failing to keep records.
- The time-clock duty and the first hours cut become enforceable in January 2027, and the reform bans any cuts to wages or benefits during the transition.
- Opposition lawmakers said the package does not clearly guarantee two weekly rest days, and workplace health experts warned that strict digital tracking could raise anxiety and fatigue without disconnection policies.
