Mexico's phased reduction of the standard workweek should not be implemented through a single scheduling change for the entire workforce. Production teams, office staff, supervisors, remote employees and customer-facing roles may share the same legal framework while requiring different operational solutions.
The Federal Labor Law amendments were published on May 1, 2026. The ordinary weekly maximum is 48 hours in 2026, 46 in 2027, 44 in 2028, 42 in 2029 and 40 in 2030, with no reduction in employees' salaries or benefits as a consequence. Each team needs a clear understanding of how working time is actually allocated, which operating coverage is essential and which records support the agreed schedule. Read the official decree.
A job-role matrix is therefore a more practical starting point than a company-wide announcement. It helps identify coverage needs, uneven workloads and documentation gaps before a new schedule is introduced.
A role-based approach helps employers determine where shifts must change, where after-hours availability needs clearer boundaries and where evidence of working time requires improvement.
Why each role group needs a different assessment
In many organizations, the workday is managed by "custom." There are established schedules, but also exceptions, informal practices, and different criteria across departments. As long as the model remains stable, those differences may seem manageable. But when the workday limit changes, these inconsistencies become more visible.
A company may have operational workers with fixed shifts, administrative staff with regular hours, trusted personnel with extended availability, sales staff working in the field, hybrid teams, remote staff, technicians who handle emergencies, and executives who do not follow a conventional schedule. Expecting everyone to migrate to the same scheme can create problems.
In some cases, the problem will be operational; in others, documentation-related; and in others, financial. There may also be risks to internal equity if certain groups perceive that the change benefits them less or imposes greater burdens on them.
Segmentation helps avoid these problems. It does not mean creating privileges or arbitrary exceptions. It means recognizing that implementation must respond to the reality of each role and be documented with objective criteria.
A role-based map of implementation priorities
This matrix does not assign universal risk scores. It identifies a practical focus and a first management decision for each group.
| Role group | Key implementation exposure | First decision to review |
|---|---|---|
| Operations and shift work | Coverage gaps, handovers and unplanned overtime | Measure working hours by process and redesign coverage while respecting rest periods |
| Middle management | Extended availability, covering absences and unrecorded work | Review tasks absorbed by supervisors and overtime authorization |
| Office and administrative staff | Closings, meetings and messages extending actual work hours | Set priorities, protected work windows and approval rules |
| Remote, hybrid and field-based staff | Fragmented records or disproportionate surveillance | Adopt a proportionate method for recording time and safeguarding privacy |
| Sales and customer service | Client requests outside scheduled hours and extended service coverage | Separate commercial targets from time actually worked |
Operations: shift coverage, rest periods and working-time records
Operational personnel are usually the first group companies analyze when discussing a reduction in working hours. This is logical, especially in industries with a high concentration of shift workers. However, the analysis should not be limited to the number of hours.
The company must review how each process is covered, which roles are essential, what breaks are granted, where overtime is generated, which incidents are frequent, and what margin exists to redistribute work without affecting productivity or safety.
In industrial operations, for example, a schedule adjustment can impact production, maintenance, cleaning, security, transportation, and shift handovers. In hotels, it can affect the front desk, food and beverage, housekeeping, maintenance, and guest services. In logistics, it can affect delivery windows, loading, unloading, inventory, and supervision.
The challenge is that operational personnel usually depend on more visible time-tracking systems. Clocking in and out is controlled, shifts are defined, and absences are detected quickly. This can facilitate implementation if the company has reliable data. But it can also expose inconsistencies if the records do not match reality.
That is why the first question should not just be how many hours will be reduced. It should be what each operation needs to function correctly within the new limit.
Map coverage by process, handovers, rest periods, incidents and overtime before deciding on new shifts.

Middle management: avoiding unrecorded supervisory hours
Middle managers often fall into an ambiguous zone. They are not always treated as operational personnel, but they do not have full executive autonomy either. Supervisors, coordinators, shift leads, department heads, and operations managers often extend their availability to resolve problems, cover absences, or submit reports outside of hours.
This group can become one of the main risk points. If the company reduces the workday for operational personnel but does not redefine supervisory workloads, middle managers may absorb the pressure. They may end up filling gaps, extending their own hours, or handling incidents without a clear record.
Furthermore, there is a frequent perception that certain roles, because they involve trust or responsibility, do not require the same schedule control. That idea must be reviewed carefully. The nature of the role does not automatically eliminate the need to properly document the workday when there is an employment relationship subject to control, subordination, and time obligations.
The company must define clear rules for middle management: schedules, availability, authorization for overtime, communication channels outside of working hours, activity logs, and limits on intervention. Otherwise, implementation may shift the risk from operational staff to those in supervisory roles.
Identify work extending beyond the scheduled day; a position of trust does not automatically create a blanket exemption from all working-time rules.
Administrative staff: peaks, deadlines and after-hours availability
On the surface, administrative staff may seem like the easiest group to adjust. Their schedules are usually more stable and do not always depend on continuous coverage. However, this can lead to underestimating the risk.
Administrative areas also face work spikes, month-end closings, audits, reports, internal customer service, after-hours meetings, and constant digital communication. If a company reduces working hours without streamlining these practices, it may create invisible overtime.
Modern administrative work does not always end when leaving the office. Messages, emails, video calls, and internal platforms can informally extend the workday. Therefore, implementation must include rules regarding after-hours communication, urgent matters, authorization for additional work, and the use of digital tools.
It should also be reviewed whether administrative areas truly require the same scheme. Finance, payroll, legal, procurement, customer service, human resources, and technology may have different workloads. A uniform policy may be easy to communicate, but not necessarily efficient.
Separate predictable peaks, genuine emergencies and digital communications that extend work without prior authorization.
Remote, hybrid and mobile work: flexibility supported by records
Remote, hybrid, or mobile work poses specific challenges. When the workday does not take place within a physical workplace, the company needs clear mechanisms to verify start times, end times, breaks, and availability.
In these cases, the risk is not just a lack of control; it can also be an excess of it. Companies must balance the need to document working hours with reasonable criteria for privacy, proportionality, and trust. Not everything can be solved with digital surveillance. The system must be functional, explainable, and aligned with the nature of the position.
For remote workers, it is advisable to establish rules regarding schedules, availability, breaks, meetings, message response, and authorization for work outside of hours. For mobile or field personnel, the company must define how time is recorded when the worker visits clients, travels, handles reports, or performs activities outside of a fixed location.
The relationship between working hours and objectives must also be reviewed. A results-oriented position is not automatically exempt from working time analysis. The company needs to distinguish between operational flexibility and a lack of control. Flexibility can be maintained, but it must be documented with clear rules.
NOM-037-STPS-2023 sets occupational safety and health requirements for arrangements falling within Mexico's statutory telework regime, generally involving more than 40% of work time at a location outside the employer's workplace using information and communication technologies. Occasional hybrid work or mobile fieldwork should not automatically be classified as regulated telework. Working-time and privacy arrangements still require case-specific assessment.
Choose a proportionate means of establishing hours without assuming continuous monitoring is required or that every hybrid arrangement is regulated telework.
Sales and customer service: targets versus hours actually worked
Sales or customer service teams may have relevant particularities. In some cases, they work toward goals, visit clients, handle calls, participate in events, respond to messages after hours, or depend on commercial availability. This can create a blurred line between regular working hours, client management, and additional time.
The reform makes it necessary to review that boundary. If a company expects a salesperson to respond to messages at any time, attend after-hours meetings, or participate in additional commercial activities, it must analyze how that time is documented and compensated when applicable.
The same applies to customer service or support areas. In services with extended hours, the reduction of the workday may require redesigning shifts, escalation processes, and service rules. The goal should not be to shift the pressure onto the worker, but to build a sustainable model.
Set client-response hours and escalation procedures; meeting commercial targets does not replace an assessment of working time.
The implementation matrix: information needed for role-based decisions
The best way to avoid a disorganized implementation is to build a position matrix. This tool allows for the classification of staff and the definition of differentiated paths.
A useful matrix should include, at a minimum, the following elements: position, department, workplace, modality, current schedule, estimated actual schedule, target schedule, recording system, level of supervision, frequency of overtime, reliance on after-hours availability, operational impact, applicable documents, and necessary actions.
With this information, the company can identify risk groups. For example, positions with a high frequency of overtime, areas without reliable recording, middle managers with extended hours, remote staff without clear rules, or mobile workers without an adequate documentation system.
The matrix also allows for prioritization. Not all areas require the same level of intervention. Some will only need documentation adjustments. Others will require operational redesign, collective bargaining, training, technology, or changes to internal policies.
How to develop a role-based implementation matrix
Classify
Group roles by tasks, operating coverage, work arrangement and supervision, not only by job level.
Compare
Review agreed hours, actual time worked, incidents and available records against day-to-day practice.
Design
Model revised schedules, handovers, staffing and authorizations for each function and the applicable legal limit.
Validate
Review with operations, Human Resources and legal teams; test whether controls reflect the real process.
Contracts, policies and actual working time must align
A differentiated implementation will not work if company documents are not aligned. Individual contracts, internal policies, internal regulations, record-keeping systems, authorization procedures, and operational practices must all tell the same story.
If the contract says one thing, the policy another, and the operation something else, the risk increases. Authorities, employees, or courts may focus precisely on those contradictions.
Companies must review whether their contracts adequately describe working hours, work arrangements, and job positions. They should also analyze whether their policies cover remote work, availability, the right to disconnect, overtime authorization, shift changes, and attendance tracking.
The goal is not to over-bureaucratize operations, but to provide them with documentary support. A company can be flexible while still having clear rules. Flexibility without documentation can turn into vulnerability.
The same role must be reflected consistently across four records
Agreed hours, role type and applicable arrangements.
Availability, shifts, approvals and communication.
Coverage, breaks, workload and actual practice.
Evidence of time worked and relevant incidents.
Article 132(XXXIV) provides for electronic records, while the scope and exceptions are subject to general STPS rules scheduled to take effect from 2027. Employers should not assume one prescribed format already covers every role. Official decree.
A differentiated transition requires decisions and monitoring
Applying the same schedule to the entire workforce may seem quick and can facilitate internal communication, but if it does not reflect the reality of the roles, it can lead to future costs: unforeseen overtime, loss of coverage, internal complaints, record-keeping inconsistencies, pressure on middle management, or urgent corrective adjustments.
Proper implementation requires more initial work. It demands diagnosis, segmentation, and design, but it allows for the construction of a more defensible and functional model.
The 40-hour workweek reform should not lead companies to think only about reduction. It should lead them to better understand how they work: which positions are critical, which areas depend on informal availability, which processes generate overtime, which systems do not track time accurately, and which documents no longer reflect actual operations.
This information is not just for compliance; it is for better management.
A uniform policy may be easy to communicate yet difficult to sustain if it overlooks coverage requirements, after-hours work and discrepancies between documentation and real operations. Segmentation organizes management decisions; it should not create arbitrary privileges across employee groups.

You can also review the electronic working-time records framework and the role of Human Resources in implementation. Each adjustment should be assessed against the company's working arrangements and applicable rules.
