Domestic workers. Undocumented immigrants. Workfare laborers. Long regarded by traditional trade unions as "unorganizable," these and millions of other poor workers are becoming the new face of labor. An essential primer to the "other labor movement," Poor Workers' Unions presents the community/labor partnerships, workers' centers, and independent caucuses that are revitalizing labor for the twenty-first century. Making extensive use of organizational archives and interviews with organizers, activist-writer Vanessa Tait deftly illuminates key connections between the social justice movements of the last fifty years and today's most innovative labor organizing.
