Overview
- The IMSS and national SNTSS leadership applied an 8% global increase that is retroactive to October 16, 2026.
- The raise is split into 4% added to salary tabular and 4% paid as housing rent aid (Concept 11), so most employees did not receive a full 8% increase to base pay.
- The union leadership accepted the deal without a new membership vote and said it had no statutory duty to re-consult, a decision that many rank‑and‑file workers reject.
- Workers organized large protests and a national megamarch on October 30 and plan an assembly for October 31 to decide next steps while some say they will explore legal challenges.
- Because dues are calculated from total pay, the applied increase raised the absolute amount remitted to the union and has intensified demands for a 10% tabular rise and restoration of pension terms.
