The article looks at several aspects of the ethical and political dimensions of Simone Weil's writing on her experience as a factory worker in 1934-1935. It also attempts to follow the steps she would have taken to rethink oppression in relation to the gestures, sounds, looks and manifestations of the working condition. These two records are intertwined in Weil's reflections on the plight of workers. Based on a particular Marxist heritage, she problematizes oppression in a certain materiality of both the discourse and the bodies that move about in the scenario of the factory, a question that gives this thinking a relevant specificity in a certain tendency in contemporary French philosophy.
