Four major French rail unions, including CGT-Cheminots, Sud-Rail, Unsa-Ferroviaire, and CFDT-Cheminots, have announced a unified one-day strike on June 10, 2026. This collective action signals a "state of emergency" due to workplace tragedies stemming from SNCF restructuring and subsidiary creation, with unions refusing to accept these transformations and demanding genuine wage negotiations amid rising inflation, which saw a 2.2% increase in April 2026. This marks the first national rail strike of 2026 supported by all four leading unions, employing a tactic of single-day walkouts to maximize disruption, though past single-day strikes have seen limited impact due to SNCF's use of volunteer staff.
