“The clock has started” for a potential Chicago Teacher’s Union strike. That’s according to union president Karen Lewis.
The countdown to the possible strike began after the union rejected the recommendation of a neutral arbitrator to accept a contract offer from the nation's third-largest school system.
The union says the earliest a strike could begin is May 16, about a month before the last day of school. It says it also could strike in September, when school resumes for about 400-thousand students.
