Mexico Sets Dec. 14 Enforcement Deadline for 'Ley Silla' Workplace Seating Rules

Employers must update internal regulations to reflect STPS risk-based guidance covering pauses, duration, seat placement.

Overview

  • Starting Dec. 14, authorities can penalize noncompliance with fines of 250–2,500 UMA (about MXN 28,285–282,850), which can double for repeat offenses and lead to temporary suspension of activities.
  • The reform to the Federal Labor Law guarantees workers the right to sit during the workday and prohibits requiring employees to stand for an entire shift.
  • The date marks the end of a 180‑day transition period granted to companies to adapt their internal rules after the law took effect.
  • STPS issued implementation tools, including a risk-level questionnaire and three seating scenarios: at the workstation, near the work area, or in an employer-designated space.
  • Although aimed chiefly at commerce and services, STPS says the rules apply across industries, with each employer defining pause frequency and duration based on its own risk analysis.
