The point of departure for Dorota Sajewska's article is the Lumière film Workers Leaving the Factory. Sajewska regards the 1905 revolution as an unprecedented example of unity between workers' theatre and the proletariat's practices of participation in public life. Sajewska refers to manifestations, demonstrations, as well as aestheticised mass spectacles as the workers' exploration of the street as an open performance space. She places reconstruction practices referring to the October Revolution within the same order. She confronts the idea of the factory as a modern thatre stage with Alain Badiou's sketch The Factory as Event Site. The accident as a rupture in the continuity of work in the factory and the disintegration of the capitalist machine of exploitation becomes the source scene of the revolution and, at the same time, a repressed traumatic event.
