This paper initially presents some major historical stages of the conquest of workers'rights in France, emphasizing what led to a real official recognition of the rights in the fight to improve working conditions. During the seventies, when "flexibility" became the watchword of corporate restructuring, two laws questioning the banning of intermediation of labor and establishing a structural process of precarization of labor and employment, that changed not only the workers' economic security as the set of rights associated with the employment contract. This process unravels, in great part, the right to health of workers in the workplace, such as professional cancers, as reveals research a permanent research made in a parisian region, with patients suffering from cancer. New networks of resistance, most often internationally established and constituted on a citizenship basis organize themselves, however, about the health challenges, as addressed in the conclusion.
