A notebook, a signed list or a cardboard card are not. ## What to do with the paper You can keep using it as internal support, but it does not replace the electronic record. ## How to migrate without pain - Add your team. - Start with a week of testing in parallel. - Remove the paper once the team gets used to it. ## How long it takes With an app, setting up a branch and its team takes minutes. ## 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 - Assuming the obligation does not apply because you are a small business. - Believing a device or fingerprint is required. - Confusing the date the law took effect with the date of the STPS rules. - Reading the 2030 caps as if they already applied. - Trusting a provider that claims to be certified by the authority. ## What to do now 1. Read what article 132, section XXXIV, requires. 2. Review how you record your staff's clock-in and clock-out today. 3. Choose an electronic recording method. 4. Agree on it in writing with each person. 5. Check the STPS general rules when they are published. ## Related terms **[What is attendance control](https://sicheca.com/en/blog/control-de-asistencia).** Attendance control is any means of knowing who came to work and at what time. **[Day shift: schedule and maximum length](https://sicheca.com/en/blog/jornada-diurna).** The day shift is the one worked between 6:00 a.m. and 8:00 p.m. **[What is NOM-035](https://sicheca.com/en/blog/nom-035).** NOM-035 is the STPS standard that requires identifying and preventing psychosocial risk factors at work, such as excessive workloads and long workdays. ## Frequently asked questions ### Does scanning the notebook work? No. A photo of the paper is not a per-person record with start and end times captured electronically. ### 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 reform already in force? Yes. The reform to the Federal Labor Law took effect on May 1, 2026. The reduction in working hours starts on January 1, 2027. ### Who monitors compliance? The Ministry of Labor and Social Welfare, through inspections. ### Where do I find the official text? In the Official Gazette of the Federation of May 1, 2026 and in the current version of the Federal Labor Law published by the Chamber of Deputies. ## Legal basis and sources - Electronic working-time record: article 132, section XXXIV, of the LFT and fifth transitory provision of the decree. - Fines: articles 992, 994 and 1002 of the LFT. - [Decree amending the Federal Labor Law on the reduction of the working week](https://sidof.segob.gob.mx/notas/docFuente/5786537).
