what the afl-cio is trying to do is continue a trend they've done in the past and form organizations of nonunion workers and try to figure out ways for workers that are difficult to organize in low wage industries and industries with a lot of turn afternooover get them involved. it's going to be a question of how long the afl-cio is going to be able to commit to this. >> let's talk about the protest of walmart workers. how effective have these demonstrations been? are workers making any gains? >> it's unclear exactly where it's going. it's a long, uphill struggle. walmart has retaliated against a lot of these workers. 60 workers have been fired. so they're raising consciousness among walmart workers but walmart is fighting back at the same time. >> how much of the demonstrations themselves -- how much have they also been about big labor's search for new members? >> i think that's a big thing.
