The years between 1930 and 1979 witnessed a period of intense labor activity in Latin America as workers participated in strikes, unionization efforts, and populist and revolutionary movements. The ten original essays AEMDNMOin this volume examine sugar mill seizures in Cuba, oil nationalization and railway strikes in Mexico, the attempted revolution in Guatemala, railway nationalization and Peronism in Argentina, Brazil's textile strikes, the Bolivian revolution of 1952, Peru's copper strikes, and the copper nationalization in Chile—all important national events in which industrial laborers played critical roles. Demonstrating an illuminating, bottom-up approach to Latin American labor history, these essays investigate the everyday acts through which workers attempted to assert more control over the work process and thereby add dignity to their lives. Working together, they were able to bring shop floor struggles to public attention and—at certain critical junctures—to influence events on a national scale.
