Introduction

Reducing the workweek from 48 to 40 hours represents one of the most significant changes to the Mexican labor framework in decades.

The constitutional reform has already been approved by the Congress of the Union and the majority of state legislatures, so its publication in the Official Gazette of the Federation will mark the formal start of its implementation.

5 key points every company must consider to prepare for the 40-hour work week
Diagnose actual work hours

Identify how hours are currently worked by department, shift, and position.
Redesign operations

Adjust shifts, workloads, breaks, and staffing needs.
Measure the economic impact

Forecast costs related to hiring, overtime, productivity, and control systems.
Strengthen time tracking

Document clock-ins, clock-outs, breaks, overtime, and days worked.
Prepare to prove compliance

Maintain clear, verifiable, and consistent information for inspections or disputes.

Understanding these implications in advance allows for a transition with greater legal and operational certainty.

Important considerations

Work Week Reform: Impact and transition strategy

What changes with the 40-hour work week?
The reform reduces the weekly work limit established in Article 123 of the Constitution from 48 to 40 hours.

Its implementation is planned progressively, with the goal of allowing companies to adapt their operations without causing abrupt disruptions in the labor market.

However, even with a gradual transition, the new scheme may impact various aspects of work organization.
Aspects companies should start reviewing

Reducing the work week is not just a legal change. It also involves operational and compliance adjustments.

Key elements that companies should analyze include:

  • Shift organization: Many companies currently operate with schedules designed for up to 48 hours. The transition to 40 hours may require redistributing shifts or adjusting workloads.
  • Overtime control: When operations do not adapt to the new work schedule, overtime can increase and put pressure on labor costs.
  • Time tracking: The reduction of the weekly limit increases the importance of having reliable systems to track working time.
  • Labor documentation: Contracts, internal regulations, and internal policies must correctly reflect how the workday is organized within the company.
Business impact of the reform

Beyond its legal implications, the 40-hour workweek can have significant operational and economic effects.

Among the factors that many companies are beginning to analyze are:

  • Reorganization of work shifts.
  • Potential increase in overtime hours
  • Impact on labor costs.
  • Interaction with the tax system.
  • Operational adaptation across different sectors.

For this reason, more and more organizations are evaluating in advance how to prepare for their transition to the new work schedule scheme.
