CONSTITUTIONAL REFORM REDUCTION OF THE WORKWEEK
On March 3, 2026, Mexico published the constitutional reform that will gradually reduce the maximum workweek from 48 to 40 hours per week. Although the decree has already entered into force, 2026 will remain at 48 hours, and the effective reduction will begin in 2027 (46 hours), reaching 40 hours in 2030. The approved text did not include two mandatory rest days per week; it preserves at least one rest day for every six days worked, modifies the constitutional rules on overtime by establishing a maximum of 12 hours per week, which may be distributed over a maximum of 4 days, and gives Congress 90 days to harmonize the secondary legislation. For companies, the main message is clear: there is no immediate operational change in 2026, but the preparation period has already begun.
