Mexico Labor Law Changes and Leave: How to Stay Compliant
Mexico's labor rules are moving on two fronts at once: working time is being cut in stages through 2030, and leave rules such as vacation have already been rewritten. If your Mexico policies sit in a spreadsheet, someone has to notice each change and recalculate. Planleave is the leave compliance platform that does this for Mexico and 13 other countries in South America. See how Planleave handles leave compliance.
Which Mexico labor law changes affect leave and working time right now?
Two reforms matter most: the constitutional amendment that phases the workweek down to 40 hours, and the 2023 vacation reform that doubled minimum vacation. The workweek amendment was published in Mexico's Official Gazette on March 3, 2026, and the Federal Labor Law was amended to implement it, with publication reported on May 1, 2026 (Holland & Knight; Littler). The vacation reform has applied since January 1, 2023 (Littler).
When does Mexico's 40-hour workweek take effect?
The reduction starts on January 1, 2027 and finishes in 2030, with no cut to pay or benefits. The maximum weekly hours are 48 in 2026, 46 in 2027, 44 in 2028, 42 in 2029 and 40 in 2030 (Holland & Knight; Baker McKenzie). The one paid rest day for every six days worked is unchanged.
For a compliance buyer, 2026 is the preparation year. Contracts, work rules and any collective agreements need review before the first step down.
What do the new overtime and time-record rules mean for employers?
Overtime is capped and paid at higher rates, and employers must keep an electronic record of each workday's start and end. Double-rate overtime is capped at nine hours a week in 2026 and 2027, rising to 12 hours by 2030, and combined ordinary and overtime hours may not exceed 12 per day (Baker McKenzie). The electronic time record takes effect January 1, 2027, and the Ministry of Labor is expected to issue implementing rules (Littler).
Hours and overtime are a payroll and timekeeping matter. The point for your leave program is that Mexican authorities are paying closer attention to how employers record and apply worker entitlements, so your leave records need to be just as defensible.
Does Mexico's 2023 vacation reform still catch employers out?
Yes. Policies and contract templates copied from before 2023 still show the old six-day baseline, but the statutory minimum is now 12 days in the first year, rising with seniority, plus a vacation premium of at least 25%. Our Mexico leave law guide lays out the full schedule, and the Littler summary of the vacation amendments is a useful second source.
This is the typical compliance gap in a mixed workforce: a law changes, and balances for existing employees keep running on the old rule until someone catches it.
How do you stay compliant as Mexico's leave rules change?
You need a way to hear about each change, verify it, and apply it to every employee's entitlements without re-entering data. A short checklist:
· Name an owner for Mexico law monitoring, so a change reported in the press is checked against an official or law-firm source.
· Re-check every Mexico policy and contract template against the current statutory schedule.
· Recalculate entitlements by hire date, since seniority drives vacation.
· Keep a record of when each rule changed and who signed off.
Planleave is built for this. The AI Regulatory Monitor runs a six-step validation of each leave-law change, signed off by a person in your company. The same monitor feeds the calculation engine, so leave follows the employee's hire date and moves to the next policy automatically, with carryovers automated.

Frequently asked questions
What is the 40-hour workweek law in Mexico?
It is a constitutional amendment, published in the Official Gazette on March 3, 2026, that lowers the maximum workweek in stages from 48 hours in 2026 to 40 hours in 2030, starting on January 1, 2027, without reducing pay or benefits.
Did Mexico change its vacation law?
Yes. Since January 1, 2023, the minimum is 12 vacation days in the first year, up from six, and employees receive a vacation premium of at least 25%.
Do Mexico's labor law changes affect leave balances?
Vacation entitlements changed directly in 2023. The workweek reform changes working time rather than leave days, but it increases scrutiny of how employers record and apply employee entitlements, so Mexico policies and contracts should be reviewed.
How can a company monitor Mexico labor law changes?
Assign an owner, verify each change against an official or law-firm source, and apply it to every employee's entitlements. Planleave's AI Regulatory Monitor validates each leave-law change in six steps, with sign-off by a person in your company.
