Ballots must reach the National Labor Relations Board regional office in Alabama by March 29 to be counted. Jonathan Rosenblum is the author of Beyond $15: Immigrant Workers, Faith Activists, and the Revival of the Labor Movement. He also works as a community organizer for Seattle City Council member Kshama Sawant. We spoke with Jonathan Rosenblum on March 16.
