CHICAGO - Chicago Mayor Rahm Emanuel has asked a state court to force the city's teachers back to work. Emanuel said over the weekend that the strike is illegal because it endangers students' health and safety.

The Chicago Teachers Union says the mayor's court action amounts to more bullying.

Meanwhile, union delegates for striking Chicago teachers are scheduled to meet today to decide whether to end the work stoppage. The strike entered its sixth school day yesterday and has kept around 350,000 students out of class.

If union delegates call off the strike, students could be back in class by tomorrow.
