Negotiators for Chicago Public Schools and the Chicago Teachers Union failed to come to a contract agreement despite weekend bargaining sessions, though both sides agree progress has been made.

Chicago teachers take to the picket lines. Will the city delay the start of legal pot sales? A federal probe into ComEd widens. And the Bears try to bounce back against the Saints. 

As teachers hit the picket lines for the second day, the city called on Chicago Teachers Union leaders to spend more time at the negotiating table in order to reach a deal. 

The Chicago Teachers Union expects all of its members to be on picket lines during their ongoing strike. Breaking ranks could cost teachers their job.

As Day One of the teacher strike ended, Chicago Teachers Union leadership strongly criticized claims made by Mayor Lori Lightfoot that the union lacked urgency to end the work stoppage.   

Bargaining sessions between the Chicago Teacher's Union and the city started late and ended early on Thursday, the first day students missed classes with their teachers on strike, causing Mayor Lori Lightfoot to question the union’s sense of urgency. 

Chants of “fair contract!” and “Mayor Lightfoot, get on the right foot!” rang through the air outside Chicago Public Schools around the city on the first morning of the Chicago Teachers Union and SEIU support staff walkout. 

It's official: Chicago Public Schools teachers are going on strike after CPS and the Chicago Teachers Union failed to reach a contract agreement. Teachers and support staff planned to hit the picket lines at 6:30 a.m. Thursday. 

“Chicago Tonight” speaks with four parents of CPS students who have different opinions about the negotiations between the city and its teachers union. 

Mayor Lori Lightfoot and Chicago Public Schools CEO Janice Jackson said they believe the Chicago Teachers Union’s House of Delegates will vote to go on strike Wednesday evening.

Time is running out for Chicago Public Schools to reach a deal with the Chicago Teachers Union on a new contract. 

Negotiators took a break from the bargaining table Monday as thousands of teachers and school staff rallied in hopes of securing what they called a “fair contract.” 

How will a possible walkout affect classrooms, building access and after-school activities across the city?

A teachers strike could be just days away. Illinois Republicans break from President Trump over Syria. New details on federal raids of the suburbs. And the Bears lick their wounds after a loss in London.

After another day of bargaining, negotiators for Chicago Public Schools and the Chicago Teachers Union appear no closer to averting a planned Oct. 17 teachers strike.

The Chicago Teachers Union has insisted that its next contract with the city include not just raises for teachers, but a host of other commitments. But with a possible strike looming, will those demands hold up?
