That way a clock-in at 10:00 pm does not show up as late. ## What makes rotation complicated - Each shift has a different maximum: 8, 7.5 or 7 hours. - Late handoffs generate overtime. - The rest day moves. | Shift | Schedule | Daily maximum | | --- | --- | --- | | Day | Between 6:00 am and 8:00 pm | 8 hours | | Night | Between 8:00 pm and 6:00 am | 7 hours | | Mixed | Both day and night, with less than 3 and a half night hours | 7 and a half hours | Articles 60 and 61 of the LFT. ## What to check every week Who worked a double shift and who did not rest. ## The reform in one minute The reform has two parts. On March 3, 2026, article 123 of the Constitution was amended to set the 40-hour workweek. On May 1, 2026, the Federal Labor Law was amended, which is where the detail is. - The maximum working week drops from 48 to 40 hours, two hours per year, between 2027 and 2030. - Overtime has a weekly cap: it is paid at double time up to the cap and at triple time for up to 4 more hours. - Each company must electronically record the start and end time of each person's workday. - Not keeping that record is fined 250 to 5,000 UMA. - Salary and benefits cannot go down because of the reduction in hours. What remains pending are the STPS general rules, which will define who the record applies to and what exceptions there will be. They take effect on January 1, 2027. | Year | Maximum working hours | Double-time overtime | Triple-time overtime | | --- | --- | --- | --- | | 2026 | 48 h | 9 h | 4 h | | 2027 | 46 h | 9 h | 4 h | | 2028 | 44 h | 10 h | 4 h | | 2029 | 42 h | 11 h | 4 h | | 2030 | 40 h | 12 h | 4 h | Decree published in the Official Gazette of the Federation on May 1, 2026, second and fourth transitory provisions, and article 68 of the LFT. Each change applies from January 1. ## Common mistakes - Implementing the record without explaining it to the team. - Adjusting clock-ins to match the shift. - Not having someone who reviews every day. - Leaving out managers and remote staff. - Measuring only tardiness and not hours worked. ## What to do now 1. Gather the actual hours by position. 2. Present to management the effect of the 46-hour workday. 3. Write or update the overtime policy. 4. Choose the recording system and run a one-week trial. 5. Communicate the change and sign the agreement. ## Related terms **[INFONAVIT contributions: what they are](https://sicheca.com/en/blog/aportaciones-al-infonavit).** The INFONAVIT contribution is 5% of each person's contribution base salary, paid by the company. **[What the UMA is and how much it is worth](https://sicheca.com/en/blog/que-es-la-uma-y-cuanto-vale).** The UMA is the Unit of Measure and Update (Unidad de Medida y Actualización): the peso reference for calculating fines, contributions and procedures. **[Night shift: schedule and maximum length](https://sicheca.com/en/blog/jornada-nocturna).** The night shift is the one worked between 8:00 p.m. and 6:00 a.m. ## Frequently asked questions ### Is working a double shift legal? Only if the total does not exceed 12 hours in the day and the overtime is paid. ### Does this replace the advice of a lawyer? No. It is general information. For decisions about your company, consult a labor lawyer. ### Does the law require a particular system? No. It asks that the record be electronic and include the start and end time for each person. ### What happens when the STPS publishes its rules? They will specify who the record applies to and its exceptions. It is worth checking them as soon as they appear in the Official Gazette of the Federation. ### Is the maximum workday per day or per week? There are two limits: a daily one, which did not change, and a weekly one, which drops from 48 to 40 hours between 2027 and 2030. ## Legal basis and sources - Electronic working-time record: article 132, section XXXIV, of the LFT and fifth transitory provision of the decree. - Working hours: articles 58 to 64 of the LFT and second transitory provision of the decree. - UMA value: INEGI, published every January in the Official Gazette of the Federation. - [Decree amending the Federal Labor Law on the reduction of the working week](https://sidof.segob.gob.mx/notas/docFuente/5786537).
