Working-time record by WhatsApp: how it will work
Short answer
It means recording clock-in, break and clock-out by sending a message, without opening another app. In Sicheca it will be available soon.
Who it suits
Teams that already use WhatsApp all day and prefer not to install or remember one more thing.
What stays the same
The same per-person record and the same report.
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
- Comparing the purchase price and not the cost of operating.
- Not testing the tool with the real team.
- Forgetting the staff who do not work on site.

What to do now

- Try two options for a week.
- Ask the team which one they used without help.
- Check how you export your data.

Frequently asked questions
Does a WhatsApp group work as a record?
No. Loose messages in a group are not a per-person record that you can hand over.
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.
