This paper helps us analyze the conditions of the emergence of the Rassemblement de la Jeunesse citoyenne (RAJE citoyenne), a non violent direct action coordonated by the Regroupement des Auberges du coeur du Québec (RACQ). The RAJE is a young adults movement who represent a collective response to the difficulties about the access to social assistance and work or schools programs. The authors describe the origins of this "precarious" movement. They are also interested in the preminant role of the RACQ, founder and leading source of support of the RAJE. Finally, they reflect the challenges of structuring a space for citizen participation.
