The transition to the 40-hour workweek in Mexico It is putting a new focus on the way companies record, validate, and manage working time.

The challenge does not solely consist of having a timekeeper or recording entries and exits. For organizations with hundreds or thousands of employees, different shifts and distributed operations, the real complexity lies in ensuring that information about days off, incidents, and overtime is accurate and up-to-date. Precise, consistent and verifiable.

That's how he explained it Tomás Kachadourian, Director of Business Intelligence at InfoBlock, In a publication of AM, At the event, experts analyzed the changes that companies will have to consider in the context of the gradual reduction of the working day. LE2R120926_06

The electronic registration will be part of the new working environment

The reduction of the working day will be implemented gradually starting in 2027 until it reaches 48 hours per week. 40 hours per week in 2030. The Secretariat of Labor and Social Security also points out that labor inspection will be strengthened through the Electronic record of the workday, whose specific provisions will be regulated by the labor authority. Government of Mexico

This significantly changes the conversation for companies.

Recording that a collaborator entered or left at a certain time is only the first level of information. In practice, shifts change, workdays vary, leave is granted, absences occur, breaks are taken, operational issues arise, and overtime is required.

Each of these variables can modify the final result that ends up in the payroll.

Therefore, rather than simply Digitizing the attendance control, Organizations need to have complete traceability of working time.

Having records does not mean having reliable information

Many organizations already use electronic mechanisms to record the attendance of their employees. However, this does not necessarily eliminate errors.

Sudden changes in operations, shifts that do not coincide with what was planned, unauthorized incidents not promptly reported, or incorrect calculations of overtime can lead to differences between:

• what really happened in the operation;
• what was recorded;
• what was authorized;
• and what was finally paid in salary.

According to Kachadourian, this is one of the main challenges for companies: the quality of the information, Not only the existence of an electronic record.

To respond to a labor review, the organization needs to be able to reconstruct what happened and demonstrate how each employee's regular and overtime hours were calculated.

Entries, exits and overtime must form a single trackable process.

The information related to entrances, exits, breaks, shifts and overtime It is particularly relevant because it allows the workday actually worked to be compared with the information used to calculate the payment.

In this context, time management systems need to go beyond storing markings.

They must be able to apply the labor and operational rules of each organization, detect inconsistencies, and maintain the necessary evidence to validate each incident.

The STPS has indicated that the electronic registration will be one of the mechanisms used to strengthen inspection and verify compliance with the new working hour limits. Government of Mexico

When the operation is 24/7, the planned outcome is almost never exactly what happens.

The complexity increases especially in companies that work continuously.

Manufacturing, logistics, retail, food and beverage, healthcare and other industries rely on shifts, coverages and personnel movements that can change throughout the day.

An absence can lead to a change in shift. An extraordinary operation may require more time. A collaborator can temporarily cover another position.

If these changes are managed manually, the supervisor ends up spending a significant portion of their day reviewing incidents and correcting information.

According to metrics shared by InfoBlock in publication of AM, A supervisor responsible for 50 people can devote up to five hours per week managing their staff's time. With an automated ecosystem, that process can be reduced to approximately 20 minutes. LE2R120926_06

From attendance control to time management automation

Technology allows for much of this validation to take place before it reaches payroll.

The process begins with capture. Learn Free to register the working day from the beginning, Before associating the records with the rules and the changes of the operation.

With TimeBlock, For example, the information generated during the operation can be integrated with shift rules, incidents, and overtime to identify differences and facilitate their validation.

According to the information presented by InfoBlock in the publication, this type of implementation can reduce the 15% errors associated with the payment of overtime.

The goal is not just to automate an administrative task.

It is about ensuring that Human Resources, Operations and Payroll work with the same source of information and that each data can be traced from the moment it is generated until its final impact.

The quality of the data will be as important as the registration itself.

The transition to 40-hour workweeks forces companies to review how they currently manage their workdays.

Some questions are particularly relevant:

• Do the records reflect what really happens in the operation?
• Are the shift changes documented?
• Can extraordinary time be tracked from its origin to payment?
• Are the incidents validated in a timely manner?
• Do HR and Payroll departments work with the same information?
• Can the company explain and verify each calculation before a review?

The gradual reduction of the workday represents an opportunity to resolve these inconsistencies before the new regulation is fully implemented.

Because in the new work environment, Recording the time will not be enough: it will be necessary to prove that the data is correct..
