Mexico’s ‘Ley Silla’ Is Now Fully Enforceable, Labor Ministry Says

STPS sets compliance checks through its 2026 inspection program following the 180‑day transition.

Overview

  • As of December 15, 2025, employers nationwide must comply with the rule for workers who perform tasks standing, regardless of sector.
  • Workplaces must provide enough seats with backrests at workstations or nearby areas and define rest pauses and seating use within updated internal workplace rules.
  • STPS will verify implementation as part of its 2026 Annual Inspection Program, with oversight beginning immediately through scheduled inspections.
  • Workers can report violations to PROFEDET, call 800 717 29 42, email inspeccionfederal@stps.gob.mx, or file online via SIQAL (siqal.stps.gob.mx).
  • Noncompliance is subject to administrative fines measured in UMAs—with reported ranges varying across outlets—and repeat offenses can lead to temporary suspensions; supporters cite INEGI data that roughly 3 million standing workers could benefit.
