Union Polls Chicago Teachers In Advance Of Strike Vote

The Chicago Teachers Union polled its 25,000 members Thursday on questions involving the school board as part of what one official called a "dry run" for a potential strike vote.

Union officials said they undertook the poll in part to figure out logistics for a strike vote if negotiations with the district break down. Under a state education reform passed last year, the union would need to get approval from 75 percent of its total membership before a strike could occur.
