The Mexican Work Week: 48-Hour Rules Today, 40 Hours by 2030

In the United States, the 40-hour work week has been the law since 1940. As early as 1938, Congress passed the Fair Labor Standards Act, which basically required employers to pay employees overtime if they worked more than 44 hours per week. In fact, going back a little further, Henry Ford began advancing the idea of a shorter work week in 1914 when he scaled back from a 48 to a 40-hour work week. It was his belief that longer hours were counter-productive causing workers to become fatigued and more prone to mistakes. Why then, do some countries, like Mexico, still have a 48-hour work week? That’s a fair question and one that deserves an answer from those of us who live in Mexico and reap the benefits of the 48-hour work week.

Updated August 2026: Mexico’s 48-hour work week is being phased out. A constitutional reform published on March 3, 2026 lowers the legal maximum to 46 hours in 2027, 44 in 2028, 42 in 2029, and 40 hours in 2030. Everything below on shifts, paid holidays, vacation premium and the Christmas bonus remains in force, and wages and benefits cannot be cut as hours fall.

For U.S. companies evaluating nearshore outsourcing in Mexico, understanding local workforce structure is part of evaluating coverage, scheduling, continuity, and support reliability.

Mexico’s 48-Hour Work Week: The Current Rules

Mexico’s Labor Laws dictate the terms of the nation’s work week and mandatory pay and holidays. Mexico’s workday is divided into three shifts. Here’s how they break down:

1. The Day shift: The work day for the Mexican worker is eight hours and that eight-hour shift fits into a flexible 14-hour work day beginning at 6:00 am and ending at 8:00 pm.
2. The Nightshift: The night shift for Mexico’s workers happens within the 10-hour window of time between 8:00 pm and 6:00 am.
3. The Mixed shift: This is also a 7 ½ hour shift that covers part of the day shift and 3 ½ hours of the night shift.

In the U.S., these shifts are commonly known as days, nights and swing-shift and most likely cover a very similar time-span. Each work shift is paid the same wage but accounts for the slightly shorter work day making up the mixed and night shifts. Any worker who exceeds the legal 8-hour work day is compensated with overtime pay.

Here’s where it’s different; Mexico gets paid time off!

• Vacation time: Employees can request off an annual vacation of at least 6 working days and add 2 working days every following year. After 4 years, the 2 days will be added every 5 years.
• Vacation premium: Employees get a minimum of 25% salary as a vacation premium and are paid for the vacation time accrued.
• Christmas Bonus: Companies in Mexico are required to pay 15 days salary during the Christmas holidays under Mexico’s Labor Law.
• Sunday Rest Day: Mexican workers have a legally prescribed six-day work week of 48 – 42 hours depending on their shift and receive payment for seven days.
• Rest Day Premium: If an employee works on Sunday, or a seventh day, he or she will receive an added 25% percent more of the regular daily wage.

In addition to these vacation and holiday benefits, Mexico observes several national paid holidays throughout the calendar year, including New Year’s Day, Constitution Day, Benito Juarez Birthday, Labor Day, Mexican Independence Day, Revolution Day, federal transition holidays when applicable, and Christmas Day.

The Benefits of This Work Week

For those of us who live in Mexico, we have found this 48-hour work week to be very beneficial. Here’s why:

• Flexibility: With the work day divided into three shifts, we have flexibility. We can structure our schedule to work with our family routine.
• Rest Day: Most industries take Sunday as a rest day, meaning that the majority of Mexican families can enjoy a quiet day together.
• Time off: There are a number of National Holidays observed throughout the calendar year that requires companies to give employees a paid day off.

Although our work week is longer, we have the benefit of enjoying a generous vacation schedule that provides the rest and rejuvenation needed after many weeks of hard work. Additionally, because our labor laws set limits on overtime, we all avoid the inevitable burn out that comes with working too much. Most employers in Mexico, including Centris, faithfully adhere to those overtime restrictions guarding against fatigue in the workplace. When employees feel that the work-life balance is honored, then a slightly longer work day feels very doable and even easy.

For contact center operations, the practical benefit is scheduling resilience. A well-run nearshore team can support extended hours, shift planning, bilingual coverage, and seasonal volume without relying only on expensive domestic staffing models.

What Changes: Mexico’s 40-Hour Work Week Transition

On March 3, 2026, Mexico published a constitutional amendment reducing the maximum legal work week from 48 hours to 40. The reduction is phased in over four years rather than applied all at once:

Three points matter for anyone staffing a team in Mexico. First, the reform does not require two rest days per week: the existing structure of at least one rest day for every six days worked stays in place, so six-day schedules remain legal. Second, wages and benefits cannot be reduced as hours come down, which means the effective hourly cost of Mexican labor rises across the transition. Third, the vacation, vacation premium, Christmas bonus and Sunday premium rules described above are unchanged.

For U.S. companies running or planning nearshore operations, the real question is not whether the hours change but who absorbs the work of adapting to them. An in-house team in Mexico has to re-plan shifts, overtime thresholds and coverage windows four separate times between 2027 and 2030. An established outsourcing partner treats that as routine workforce management.

Centris has run bilingual contact centers in Mexico for over 30 years, with operations in Monterrey and Aguascalientes. Shift structure, overtime thresholds, holiday coverage and the 2027 to 2030 hour reduction are our compliance burden to manage, not yours. If you are evaluating nearshore contact center outsourcing in Mexico and want to know how these labor rules affect coverage, cost and continuity at your actual volume, we can walk you through it.
