Article 132, section XXXIV, of the LFT explained

Short answer

Section XXXIV of article 132 requires recording each worker's workday electronically, with start and end times, and providing it to the authority when required.

Its three parts

  • The obligation: the electronic record per person.
  • The mandate to the STPS: to issue general rules on scope of application and exceptions.
  • Evidentiary value: it constitutes full evidence if it was agreed between the parties.

Since when it has existed

Since May 1, 2026.

What it connects to

With article 994, section IV Bis, which sets the fine.

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.

Common mistakes

  • Assuming the obligation does not apply because you are a small business.
  • Believing a device or fingerprint is required.
  • Confusing the date the law took effect with the date of the STPS rules.
  • Reading the 2030 caps as if they already applied.
  • Trusting a provider that claims to be certified by the authority.

What to do now

  1. Read what article 132, section XXXIV, requires.
  2. Review how you record your staff's clock-in and clock-out today.
  3. Choose an electronic recording method.
  4. Agree on it in writing with each person.
  5. Check the STPS general rules when they are published.
