Attendance control for gas stations: how to comply with the law

Short answer

A gas station can meet the electronic working-time record requirement with a QR code printed on site, which each person scans with their phone. The law requires recording each person's start and end time; it does not require a wall-mounted time clock.

How work happens at a gas station

A gas station employs attendants, store cashiers and shift managers, with three shifts, 24 hours a day, every day. That brings three challenges for measuring working hours:

  • They operate nonstop with rotating shifts.
  • Attendants change shifts every week.
  • There are fixed night shifts.

What the law requires of gas stations

Since the 2026 reform, the Federal Labor Law requires recording electronically the start and end time of each worker's workday (article 132, section XXXIV). Failing to do so is fined 250 to 5,000 UMA. The STPS will define who it applies to and what exceptions there will be. The details are in the reform guide.

Night shifts. A night shift lasts 7 hours at most, one less than a day shift. It helps if the record separates night hours from day hours.

Sundays. Someone who works on a Sunday is entitled to a premium of at least 25% of one day's wage. The record tells you which Sundays each person worked.

Staff turnover. Each new person must clock in from their first day. With an app, registering them takes minutes.

How to record working time at a gas station

  1. Register the workplace and its shifts.
  2. Print the QR code and post it at the entrance or next to the register.
  3. Each person scans it on arrival, when leaving for a break and when going home.
  4. At the end of the day you review what does not add up and download the report whenever you need it.

Example. The attendant on the 10:00 pm to 6:00 am shift works 8 hours at night; the maximum for that shift is 7.

Calculate the Sunday premium

25% of one day's salary for each Sunday worked.

Legal minimum: 25% (article 71 of the LFT).

How to do the math by hand

With $400 per day, the premium for one Sunday is 400 × 25% = $100. If the person worked all four Sundays of the month, it is $400.

Common mistakes at a gas station

  • Keeping attendance from memory or in a notebook.
  • Recording the clock-in and forgetting the clock-out.
  • Not separating night hours, which have a lower daily maximum.
  • Not identifying which Sundays each person worked.
  • Leaving new people without a record during their first days.

What to check every day and every week

Every day.

  • Who did not record their clock-in or clock-out.
  • Shifts that went over their daily maximum.
  • Departures later than planned.

Every week.

  • Each person's overtime against the weekly cap.
  • Sundays worked, for the Sunday premium.
  • Days when someone came close to 12 hours.
  • Rest days that were actually taken.

How much an overtime hour costs: example in pesos

Suppose a daily wage of $400 on a day shift. The ordinary hourly rate is $50. One overtime hour at double time costs $100 and one at triple time, $150. If a person works 9 overtime hours in a week in 2027, that is $900 extra.

It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions

Does a gas station need to buy a time clock?

No. The law requires an electronic record of working time, not a device. An app on a phone complies.

What options are there for recording working time?

An app on each person's phone, a shared tablet or a clock connected to a system. All three comply if they generate an electronic record per person, with a start and an end time.

How are shifts that cross midnight recorded?

Clock-in and clock-out are saved with their actual date and time, and the hours are added up even if the day changes.

How do I know how much Sunday premium to pay?

With the record you know which Sundays each person worked; the premium is at least 25% of one day's wage.

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.
