Labor Unions and Undocumented Immigrants: Local Perspectives on Transversal Solidarity During DACA and DAPA.

National labor unions in the United States have formally supported undocumented immigrants since 2000. However, drawing on 69 interviews conducted between 2012 and 2016 with union and immigrant rights leaders, this article offers a locally grounded account of how union solidarity with undocumented immigrants has varied notably across the country. We explore how unions in San Francisco and Houston have engaged with Obama-era immigration initiatives that provided historic relief to some undocumented immigrants. We find that San Francisco's progressive political context and dense infrastructure of immigrant organizations have enabled the city's historically powerful unions to build deep institutional solidarity with immigrant communities during the Deferred Action for Childhood Arrivals (DACA [2012]) and Deferred Action for Parents of Americans (DAPA [2014]) programs. Meanwhile, Houston's politically divided context and much sparser infrastructure of immigrant organizations made it necessary for the city's historically weaker unions to build solidarity with immigrant communities through more disparate channels.
