More than 30,000 CPS teachers and support staff are on strike. Gathering in front of schools across the city with signs, teachers say they're fighting for better schools and for their students.
Some key issues for the Chicago Teachers Union are getting smaller class sizes; getting a written commitment for more nurses, librarians and social workers; and reducing counselor caseloads.
Here are some scenes from the strike. You can follow all latest developments with WBEZ's live blog.
