Promoters and staff from other companies at your location
Short answer
Working time is recorded by whoever employs the person. A brand's demonstrator, a security company's guard and subcontracted cleaning staff record with their own employer, not with you.
What is on you
Verify that your specialized services provider is registered and complies with regard to its staff.
The risk zone
When you give the orders, set the schedule and discipline, outside staff start to look like yours.
For the one providing the service
Their workers clock in from their phones at your premises. That way it has evidence for its client and for the authority.
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.
