Entry into Force of the Working Week Reduction – January 1, 2027

Dear Clients:

We would like to remind you that, as part of the working week reduction reform, the first stage of its gradual implementation will become effective on January 1, 2027, reducing the maximum weekly working hours from 48 to 46 hours, without any reduction in employees’ salaries or benefits.

Additionally, the reform establishes the obligation for employers to maintain an electronic working-time record capable of identifying, among other information, the starting and ending times of each employee’s working day.

In this regard, the Ministry of Labor and Social Welfare (STPS) is expected to issue, during October 2026, the regulations and guidelines governing the implementation of the electronic working-time record, including its scope of application, technical and operational requirements, and any applicable exceptions.

Accordingly, we recommend that companies begin reviewing their work schedules and working-time arrangements, individual and collective bargaining agreements, Internal Work Regulations, and current attendance-recording systems in preparation for the new requirements.

Once the STPS issues the corresponding guidelines, we will promptly provide you with an update regarding their content and the measures that should be implemented to ensure compliance.
