"Worker centres, community-based mediating institutions that provide support to low-wage workers in the United States, have grown from five in 1992 to 160 in 2007. With unions increasingly targeting low-wage immigrant workers employed in non-footloose industries for organizing drives, it would seem that worker centres and unions are a match made in heaven. On the ground, however, it has been more of a mismatch. This article examines the underlying sources of the mismatch embodied in the structures, ideologies and cultures of worker centres and unions."
