Update, 8:15 p.m.:

After a weekend of productive bargaining, CTU president Jesse Sharkey said he had his hopes dashed by a letter from Mayor Lori Lightfoot and CPS CEO Janice Jackson asking teachers to come back to work.

In response, the union’s big bargaining team, which Lightfoot has suggested is unwieldy, will skip talks tomorrow and will take to the picket line. Leadership will continue to negotiate.

SEIU Local 73, which represents school staff, suggested talks today were even less productive than with CTU. “We came here today ready to work through the open issues,” Local 73 President Dian Palmer said Monday night. “The mayor and CPS committee walked out after 12 minutes with no proposals, no ideas and no solutions.”

A source close to the mayor's team said SEIU were the ones that ended the meeting after the district did not increase their offer, and that no one stormed out. While not actively bargaining, the two sides have been in active talks. "The issues left to resolve are finite. We think we can get to a deal quickly," the source said.

Lightfoot suggested earlier in the day that the holdup was because of solidarity between the unions. “SEIU has made it very clear they’re not doing anything until CTU moves,” the mayor said when asked the status of negotiations with the unit that represents 7,500 school workers, “which I think is a mistake, but that’s their choice.” Their meeting Monday was the first bargaining session since the strike began.

As public school workers and the city continue to negotiate a new teachers contract, the Chicago Teachers Union has had a consistent target for some of its ire: developer Sterling Bay and its Lincoln Yards development.

SEIU toured the TIF area today as part of a rally, and the teachers union has described the $1.3 billion in potential city assistance for the development as an unnecessary “giveaway” for a “mega-luxury real estate development” that could single-handedly fund the union’s contract demands.

The union says the city assistance is both a sign of the city’s prioritizing the wealthy over the needy, and that the money should specifically be “redirected to our school communities.”
