Since cooperatives first appeared in the 19th century, history has shown the diversity of this movement. This contribution highlights the role of Business and Employment Cooperatives (BEC) i.e. a peculiar kind of cooperative of solo self-employed workers. They are one kind of self-employed workers communities that appeared, among guild-like groups, unions (e.g.: Freelancer’s Union in the USA), co-working spaces, peer support networks, supportive umbrellas for freelancers, and of course, own-account workers cooperatives, among which on can find the BECs. The way the latter organize themselves in a context of growing incentives to self-employment and decline of trade unions challenges the classical debate of continuity/renewal of workers’ collective action.
