The movement, organised by the independent base union SUDD Cobas, marks the culmination of seven years of worker-led organising in one of Italy’s most exploitative sectors.

Rather than staggering actions, SUDD Cobas began coordinating simultaneous, open-ended strikes across multiple factories. ‘They could see clearly that this kind of mass support was essential.’The current round of strike days is still under way.
