Overview
- The reform published in the DOF requires every workplace to keep an electronic register of each worker’s start and end times, and this duty becomes enforceable on January 1, 2027.
- Fines for not installing or maintaining the system are set in UMAs at 250–5,000 units, which under 2026 values equal roughly 29,000 to more than 500,000 pesos and rise with annual UMA updates.
- The STPS has the authority to issue implementing rules but had not published those lineamientos as of early November, leaving key operational details unresolved for employers.
- Unanswered questions include how the register will apply to teleworking and hybrid schedules, how meal and health pauses must be recorded, and how night and discontinuous shifts will be documented and tallied.
- The timekeeping mandate is part of a wider reform that reduces the standard workweek to 40 hours by 2030 and phases overtime limits and pay increases, a change that will affect scheduling, payroll and worker rest practices.
