In the mid-1990s, for the first time in the history of the Americas, truly hemispherewide collaboration among labor organizations became possible. Yet this new political opportunity structure has not brought actors together in an undisputed new labor internationalism. This article focuses on two key sources of contention among labor organizations in the context of free trade mobilizations between 1990 and 2004: the discussions about coalition building with other civil society actors and the debates about including a social clause in trade agreements. It argues that transnational collective action occurs parallel to the continued relevance of national-level claims and targets, and that this simultaneity represents a real source of challenges, for scholars and labor organizations alike. Based on social network data and qualitative interviews in Brazil, Mexico, Chile, and the United States, the article analyzes the actions taken by labor organizations, and how these changed through time.
