Studying the political party "Les Verts" shows that creating meaning as a group, shaping identifications, and integrating actors in one collective action may be problematic. The organisation, far from representing a consensual collective identity, rather presents itself as a vessel for various identity-asserting acts. This autonomous relation to the collective, which is vindicated by its actors, allows one to understand that although many attempts at regulation are made, legitimate rules are lacking. In this negotiation process between autonomy and engagement, the sociable bond establishes, at the level of interactions, a precarious but efficient frame in which actors cooperate while leaving their antagonisms aside. Collective action thus functions as a dynamic, encompassing both the way the organization is structured and the actors' micro-adjustments, and attempting to conciliate individualistic claims and a care for efficiency, via its work on the shapes of this bond.
