A wave of historic protests struck the retail giant Wal-Mart on Black Friday — the busiest shopping day of the year. Workers and their supporters demonstrated at more than 1,000 stores. The Wal-Mart protests were organized in part by OUR Walmart, an organization backed by the United Food & Commercial Workers International Union. Nine people, including three Wal-Mart workers, were arrested at a protest in Los Angeles after they blocked traffic. We broadcast the voices of protesters in Secaucus, New Jersey, and speak to Josh Eidelson, a contributing writer for The Nation magazine.
