Overview:November 2017, North of Paris : H. Reiner-Onet cleaning company workers are fighting an exemplary battle. This 45 days strike, one of the longest in the history of the French railway, led by these men and women, ended in a decisive victory against two giants, Onet and the SNCF. One of the most impoverished sectors among railway workers, they had no previous experience with striking or organized struggle. How did they pull such a victory ? Their dermination to fight was undoubtedly the key to winning, but so are the links they forged with revolutionary activists who brought with them a tradition of fighting for workers against employers.
