Chicago school officials sought a court order to end the teacher strike that entered its sixth school day on Monday.
The move comes after teachers union representatives decided Sunday not to end a week-long walkout - despite a tentative contract deal reached by union leaders and school officials.
The move left Mayor Rahm Emanuel vowing to go to court to force teachers back to work, calling Sunday's actions by the union "a delay of choice that is wrong for our children."
Emanuel contended Sunday that the strike is illegal because "it is over issues that are deemed by state law to be nonstrikable, and it endangers the health and safety of our children."FULL STORY
