Mayor Lori Lightfoot said Thursday that the city would not add extra school days to make up for possible time lost in a teachers strike, a decision that would break with past practice in school walkouts.

“No. There’s no plan to make up any days,” the mayor told reporters at City Hall. “If you look at the CPS website on contingency plans, there’s zero plan to make up any days that might be lost as a result of a work stoppage. We want to make sure we get a deal done.”
