xi, 87 p. : col. map / This project explores the factors contributing to and hindering coalition building and cooperation between immigrant day laborers and the building trade unions in Portland, Oregon. The research is based on interviews with local labor and worker center leaders and an examination of public records and media discourse. It draws from a theoretical framework informed by Stuart Hall, Ernesto Laclau and Chantal Mouffe and their work on identity politics in new social movements. The research concludes that the lack of full success in this case was the result of a conflicting message that conveyed to workers that they shared a similar identity, while at the same time that they labored in separate industries. As a result, no shared identity was ever established and organized labor continued to view immigrant workers as outsiders. / Committee in charge: Daniel HoSang, Chairperson; Joseph Lowndes, Member; Daniel Tichenor, Member
