This week, tens of thousands of activists from around the country and around the world have descended on Detroit for the second-ever United States Social Forum.  

This year's Social Forum brings together activists from hundreds of organizations and dozens of different movements under the single banner "Another World is Possible, Another U.S. is Necessary."  

The Forum opened with a massive march down Detroit's Woodward Avenue ending at Cobo Hall. A delegation of about two dozen Steelworkers joined the march including USW District 2 Director Michael Bolton and members of USW Local 6500 who have been on strike against mining giant Vale-Inco for more than 11 months.  

Over the next three days, the Steelworkers will be hosting two workshops: "Manufacturing Builds Communities" and "Fighting Sweatshops in the Global Economy," as well as holding a fundraiser party to benefit the USW members on strike at Vale.
