Overview
- A constitutional reform sets a phased reduction of the maximum weekly workweek from 48 hours in 2026 to 40 hours by 2030 with 2026 designated as an adaptation year.
- State labor officials in Coahuila say roughly 50 companies are running adjustment exercises and the state STPS is touring regions to advise employers on scheduling and operations.
- The DOF decree explicitly bars any reduction in wages or benefits as hours fall and preserves overtime pay and other labor rights.
- The reform orders the Secretaría del Trabajo y Previsión Social to collect and evaluate implementation data but does not require public reports and a senator has proposed a law to force quarterly publication that would combine INEGI and IMSS data.
- From January 1, 2027 employers covered will have to record shift start and end times electronically once STPS issues rules, but Mexico’s 56.2% informal employment rate limits direct coverage and will complicate national measurement of hours and wages.
