Since the new millennium, scholars have acclaimed a vigorous global justice movement (GJM). Many accounts have stressed the tolerant identities of those involved in this movement, and/or the movement's horizontal decision-making structure. Consequently, formal organizations are often excluded from analysis, precluding the chance to assess systematically whether they are involved in social movement modes of coordination. The article uses deductive block modelling and inferential statistics on survey data of a broad sample of 208 western European global justice organizations to uncover their modes of coordination. I find that many organizations commonly considered integral to the GJM demonstrate organizational and coalitional modes of coordination, while formal organizations often engage in coalitional work. Organizations most densely networked, including some formal organizations, do have social movement modes of coordination: they identify with the GJM, display continuity in attendance at international protests/events, and have contentious relations with political institutions. In addition, I raise methodological considerations for future studies of social movement modes of coordination.
