Mexico's Congress has approved a plan to reduce the standard workweek from 48 to 40 hours by 2030, marking a major labor policy shift as reported by El Financiero. The reform was unanimously supported in all legislative commissions, with a phased implementation starting in 2027, according to Claudia Sheinbaum, who celebrated the achievement as a step toward social justice (La Jornada).
The Chamber of Deputies officially declared the constitutional validity of the reform, which now moves to the Senate and then to state legislatures for final ratification before enforcement begins, as noted by Lopez Doriga Digital and Fortune. The gradual reduction plan includes guarantees that salaries and benefits will not be diminished during the transition period (El Financiero).
A proposed bill to mandate a 48-hour workweek for federal deputies and senators was introduced by Movimiento Ciudadano but was rejected by Morena, who criticized the idea and backed the 40-hour standard for all workers (El Financiero). The reform also clarifies flexibility around rest days and working hours to accommodate different sectors and job types (La Jornada, El Financiero).
The legislation has sparked debate about its economic impact, particularly the challenges small and medium enterprises might face in adjusting to shorter hours without reducing productivity or increasing costs (El Financiero). Despite these concerns, lawmakers have emphasized the potential social benefits of reduced working hours for workers’ health and family life.
Next steps involve Senate approval and ratification by Mexico’s state legislatures, which will determine the timeline for full implementation and any sector-specific modifications. The reform is set to become one of Mexico’s most significant labor policy changes in recent decades, with close attention on how businesses and government offices will adapt over the coming years.
