Workday in 2030: the 40-hour week
Short answer
On January 1, 2030 the maximum workday settles at 40 hours per week, the final goal of the reform. The cap on overtime at double settles at 12.
The final limits
- Ordinary workday: 40 hours.
- Overtime at double: up to 12 per week, maximum 4 per day on 4 days.
- Overtime at triple: up to 4 more.
Two rest days?
With five days of 8 hours there are two days off. That is a result of the split: the law still asks for at least one rest day for every six days worked.
| 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.
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.
Common mistakes
- Adding up overtime by pay period (quincena) instead of by week.
- Forgetting the maximum of 4 overtime hours a day and 4 days a week.
- Not counting as working time the time a person is at the company's disposal.
- Dividing by 8 hours when the shift is night or mixed.
- Paying at double time hours that already correspond to triple time.
What to do now
- Measure actual hours for the last four weeks.
- Identify who exceeds the maximum workweek for the year.
- Redesign the shifts.
- Define who authorizes overtime.
- Check each person's cap every week.
