Attendance control for veterinary clinics: how to comply with the law
Short answer
A veterinary clinic 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 veterinary clinic
A veterinary clinic employs veterinarians, assistants, groomers and receptionists, with daytime consultations with emergencies and overnight hospitalization. That brings three challenges for measuring working hours:
- Emergencies break any schedule.
- There are hospitalized animals to care for at night.
- The team is small.
What the law requires of veterinary clinics
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.
Work peaks. Overtime has a weekly cap: 9 hours at double time in 2027, with a maximum of 4 per day on no more than 4 days, and never more than 12 total hours in a day.
How to record working time at a veterinary clinic
- Register the workplace and its shifts.
- Print the QR code and post it at the entrance or next to the register.
- Each person scans it on arrival, when leaving for a break and when going home.
- At the end of the day you review what does not add up and download the report whenever you need it.
Example. The assistant who stays on duty with a hospitalized patient records a night shift.
Calculate your overtime
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
Common mistakes at a veterinary clinic
- 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.
- Covering peaks only with overtime, until exceeding the weekly cap.
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 $450 on a day shift. The ordinary hourly rate is $56.25. One overtime hour at double time costs $112.50 and one at triple time, $168.75. If a person works 9 overtime hours in a week in 2027, that is $1,012.50 extra.
It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions
Does a veterinary clinic 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 salary go down if fewer hours are worked?
No. The reform prohibits lowering wages and benefits because of the reduction in working hours.
