Onboarding new staff: the record from day one
Short answer
Add three steps to your onboarding process: adding the person to the system, explaining the record and signing the agreement.
Why from day one
The first days without a record are the hardest to reconstruct later.
Onboarding checklist
- Contract with workday and shift.
- Added to the record.
- First assisted record.
- Signed agreement.
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
- Gather the actual hours by position.
- Present to management the effect of the 46-hour workday.
- Write or update the overtime policy.
- Choose the recording system and run a one-week trial.
- Communicate the change and sign the agreement.

Yes. The cap on double-time overtime is weekly and per person.
