Employee Monitoring in Mexico: NOM-037, Remote Work and Privacy Notices

DIRECT ANSWER

Mexico regulates remote-work monitoring through two instruments: NOM-037-STPS-2023, the official standard for teleworking conditions, and the LFPDPPP, the private-sector data protection law. NOM-037 requires written telework conditions, equipment provisions and a right-to-disconnect policy; the LFPDPPP requires a privacy notice before processing employee data. Together they make "remote monitoring" a documented-conditions question before it is a software question.

NOM-037: THE TELEWORK STANDARD

Mexico's telework standard, in force since late 2023, applies to employees who work more than 40 percent of their time remotely. Its requirements that touch monitoring:

- WRITTEN CONDITIONS: the telework arrangement must be documented - equipment, connectivity, schedules, contact rules

- EQUIPMENT AND EXPENSES: the employer provides the tools, including where relevant the means of supervision

- RIGHT TO DISCONNECT: employers must establish a policy defining after-hours communication rules, rest periods and vacation time

- HEALTH AND SAFETY: telework conditions include ergonomic and psychosocial provisions

- SUPERVISION WITH RESPECT: supervisory mechanisms may be used, but they must be consistent with the documented conditions and with dignity and privacy

The standard's logic: supervision is legitimate, but it lives inside written, negotiated-feeling conditions - not inside an app nobody discussed.

THE PRIVACY LAYER: LFPDPPP

Mexico's private data protection law requires a privacy notice (aviso de privacidad) covering what data is collected, why, how it is used, with whom it is shared, and how rights (ARCO: access, rectification, cancellation, opposition) are exercised. Employee data - including monitoring data - falls squarely inside. The notice must be available before or at the time data is collected, and it must match reality: a notice that promises no monitoring while software logs activity is a violation with a paper trail.

WHAT THIS MEANS FOR MONITORING DESIGN

1. CONDITIONS FIRST: document the telework arrangement - schedules, contact rules, equipment, and what supervision exists

2. RIGHT-TO-DISCONNECT POLICY: define after-hours expectations in writing, and configure notifications and expectations to match - monitoring that implicitly demands 24/7 availability contradicts the policy you are required to publish

3. PRIVACY NOTICE: itemized, plain Spanish, covering monitoring data and the ARCO process

4. PURPOSE LIMITATION: worktime and operational data for operational purposes; content capture requires its own justification

5. RETENTION RULES: per category, with automatic deletion where the tool allows

6. ACCESS CONTROLS: who inside the company may see what, documented

7. TRAINING: managers need to know the disconnect rules they are supposed to enforce

THE PRACTICAL SEQUENCE

- Review the telework population: who crosses the 40 percent threshold and what their conditions documents say

- Draft the privacy notice with monitoring language that matches the actual configuration

- Publish the disconnect policy and align schedules and expectations with it

- Deploy monitoring at usage level, aggregated by default

- Train managers; audit access quarterly

- Review annually against the standard and the law, both of which continue to develop

FAQ

Q: Is monitoring remote employees legal in Mexico?

A: Yes, with documented telework conditions, a compliant privacy notice, purpose-limited collection and respect for the right to disconnect.

Q: Does NOM-037 ban monitoring?

A: No - it requires supervision to be consistent with the documented conditions, dignity and privacy. It bans undisclosed, unbounded surveillance, not supervision.

Q: What is the right to disconnect in practice?

A: A written policy defining after-hours communication - rest periods, vacation, and response expectations - supported by how the company actually behaves, including how it configures and uses monitoring tools.

CONCLUSION

Mexico's remote-work rulebook is conditions-first: document the arrangement, publish the privacy notice, define the disconnect policy, then deploy usage-level monitoring that matches all three documents.
