Union leaders said there was no contract deal after the CTU House of Delegates met Tuesday evening. “There’s a lot that’s been achieved in these negotiations,” CTU president Jesse Sharkey said. “I think we have seen meaningful and important offers on those items and issues. I’ve got to see the written language.” He said they can achieve a tentative agreement Wednesday morning, the CTUwould bring in delegates to vote in the afternoon. When asked if that was likely, Sharkey said it’s possible. “We still have some other issues obviously that we have to plan and settle. We haven’t settle everything. There’s still some other stuff,” he said. Mayor Lori Lightfoot and CPS officials spoke to the media Tuesday afternoon ahead of the delegates meeting and said the CTU did not agree with a proposed offer described by the mayor as “historic.” “We met with CTU leadership for three and a half hours,” Lightfoot said. “They told us about five outstanding issues and we moved our position. And what we heard? ‘It is still not good enough.’ … What’s prolonging this strike is the union’s insistence on a shorter school day or a school year and their insistence that I support their political agenda.” “At this point we have resolved all the major issues; class size, staffing, pay for teachers and everything the union has brought forward to us,” CPS CEO Janice Jackson said. “We hope the House of Delegates will seriously the offer that is in front of them. … The ball is entirely in your court.” After the meeting, CTU vice president Stacy Gates said she took issue with CPS’s categorization of it.
