In France, the left government of the "Front Populaire" was forced by the unions to pass social laws that was not on their program, including 40h works per week, the 8h/day and the first paid holidays. The struggle of this unionize include general strike, demonstration and riot, and was sometimes repressed by the State.

The 40h weeks where already done in Italy (until the rise of the fascism), thanks to the red week. Following the death of 3 people during a demonstration against war and colonization, an expropriator general strike was made in nothern Italy by local unions. Those strike do not stop every production, but focus on the needs of the workers. For example, foods was still collectid and dispatch, including by trains, but without trade; Malatesta try to warm workers to not accept the bourgeoisie gift, but to achieve the socialization of the society. Central unions accept, and betray the revolution. That may explain why the Operaism came from Italy. And why we -anarcho syndicalist- do not trust unions with hierarchy

There is some other exemple, of cours in Spain with the CNT (20 millions people living in aracho syndicalist situation), in Ukraine with the joining force of mutualized farmers and industrial unions, and the IWW
