Gutmann Fuentes, Andrea NicoleRecent scholarship in Cold War and transnational labor history has examined the role played by U.S. organized labor in neutralizing left-wing labor movements around the world, contributing to U.S. State Department goals of anti-communist containment in the Third World. Research from both within and outside the academy has examined how the AFL-CIO, operating primary through the American Institute for Free Labor Development (AIFLD), acted to undermine the socialist Unidad Popular government in Chile, helping to set the stage for the U.S.-backed coup d’etat on September 11, 1973. However, this scholarship has suffered from a relative lack of Chilean primary source material and a failure to ground historical analyses in the local Chilean context. This has impeded a full view of how the AFL-CIO’s labor intervention project unfolded in Chile, how it was perceived and responded to by Chileans, and the extent to which it was ultimately successful. This thesis makes use of Chilean national press, books, and trade union and left-wing media, in addition to new source material pulled from the U.S. State Department and the AFL-CIO archives, to assess the successes and failures of the AFL-CIO’s labor intervention project in Chile. The thesis demonstrates that while the AFL-CIO failed to accomplish many of its concrete goals in Chile due to overwhelming opposition to its project among Chilean labor, the AFL-CIO’s relationship with particular sectors of the Chilean labor movement effectively advanced a more general political goal of fomenting labor opposition from labor in strategic sectors of the economy to undermine the Unidad Popular government, thereby contributing to the success of the 1973 coup. By examining AFL-CIO’s complicated and paradoxical relationship with the centrist Christian Democratic Party, this thesis argues that the vast majority of Chilean workers from a broad array of ideological tendencies rejected the AFL-CIO’s promotion of “free trade unionism,” an explicitly anti-communist ideology advocating that workers reject a politics of class struggle in favor of class harmony between labor and management. This thesis then demonstrates that the AFL-CIO encouraged and validated the decision of some conservative labor leaders in the stevedore labor movement to ultimately join the anti-Allende opposition. Under the intensely polarized political context of early 1970s Chile, in which conservative labor leaders faced social and political pressures to move leftward with the majority of the labor movement and to support the Unidad Popular, the decision of these labor leaders to join the right-wing opposition with support from the AFL-CIO was a significant event contributing to the 1973 coup.enThesisLatin American historyHistoryLabor relationsAFL-CIOChileCold WarLabor historyLatin AmericaUnidad Popular
