On-call duty and availability: when they count as working time
Short answer
Being reachable is not the same as working. On-call duty counts as working hours when the person cannot use their time freely or when they handle a matter. Those minutes are recorded.
Two types of on-call duty
- On site or with strong restrictions: the person must stay in one place or respond within minutes. It is time at the employer's disposal.
- Reachable: can go about their life and only responds if called. The time of each call-out counts.
How to record them
Each call-out is recorded with a start and end. If it was at night, those are night hours.
What to watch
- That nobody adds up more than 12 hours in a day.
- That the rest day is respected.
- That on-call duty rotates.
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 that someone who is not in the office has no workday.
- Requiring people to come by the office just to record.
- Recording the shift time and not the real time.
- Confusing being reachable with working.
- Over-monitoring instead of recording properly.
What to do now
- List who works outside the office and under which arrangement.
- Define for each arrangement where the workday begins and where it ends.
- Put it in writing and explain it to the team.
- Have each person record from their phone, wherever they are.
- Review late clock-outs and long days every week.

Frequently asked questions
Do you have to pay for being on call?
The law does not set a payment for availability alone. Many companies agree it as a bonus.
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.
Is overtime counted by week?
Yes. The cap on double-time overtime is weekly and per person.
