The May Day rallies set to take place this Sunday follow massive pro-labor protests in Wisconsin to protect collective bargaining rights of public workers. Since 2006, when more than million people marched across the United States against a harsh anti-immigrant bill, May Day has also become a key date of protests by immigrant rights groups. This year, labor and immigrant activists will march together in a move organizers say symbolizes their decision to join forces. We speak with Clarence Thomas of the International Longshoreman and Warehouse Union Local 10, which shut down the ports of Oakland and San Francisco on April 4 in solidarity with workers in Wisconsin. We’re also joined from Milwaukee by Christine Neumann-Ortiz, executive director of Voces de la Frontera, a key organizer behind 2006’s 70,000-strong march in Milwaukee. [includes rush transcript]
