Grenoble: possible M TAG tram and bus strikes from 12 October 2026 (notice runs to 1 January 2027)

Four unions at M TAG, the operator of Grenoble's trams and buses — FO, Solidaires, UNSA and CFE-CGC — have filed a strike notice covering Monday 12 October 2026 to 1 January 2027. The notice lets staff stop work at any time in that period; no strike days have been announced yet. A meeting with M TAG's president was set for Friday 9 October.

What to expect: nothing changes on the network until the unions call a stoppage. If they do, trams and buses in the Grenoble area may be cancelled or reduced on those days; M TAG publishes its forecast before each strike day. This page will be updated when dates are announced.

Why: the unions want pay rises to match price increases, notably for fuel, under a clause of the annual wage agreement that allows extra talks when the economic context changes. They say M TAG's management has made no proposal and blames the transport authority SMMAG: "La confiance est rompue, le préavis de grève s'impose."
