Chicago teachers strike for 9th straight day

CHICAGO (AP) — Chicago’s mayor on Tuesday accused leaders of the city’s powerful teachers union of using “political” issues to hold up a contract agreement to end a strike that has closed classrooms for nine days.

Mayor Lori Lightfoot said the Chicago Teachers Union’s bargaining team demanded “at the eleventh hour” that she support state legislation to elect rather than appoint the district’s school board, as well as changes to state law governing what the union can strike over.

“Are we really keeping our kids out of class unless I agree to support the CTU’s full political agenda wholesale?” Lightfoot said at a press conference. “If the CTU wants a deal, there’s a deal to be had right now on the table.”

The heated accusations follow several days of contentious closed-door talks seeking to settle the strike, which has kept more than 300,000 students out of classrooms since Oct. 17 in the nation’s third-largest school district.

A union spokeswoman didn’t immediately respond to a request for comment. A message posted on the union’s Twitter account said it was “just asking that the mayor stop contradicting herself and the platform she campaigned on.”

Both sides have said in recent days that they made progress on the teachers’ top priorities, including stricter limits on class sizes and additional staffing. Talks resumed Tuesday, hours after a 16-hour bargaining session wrapped up without a tentative agreement.

A representative for the teachers union suggested after the late-night session ended early Tuesday that Lightfoot could settle the dispute by committing to more resources for schools.

General Counsel Robert Bloch said the union representing 25,000 teachers is awaiting the city’s response. He says the parties have narrowed their differences, “but we’re not there yet.”

But Lightfoot and the district’s CEO Janice Jackson said Tuesday that union leaders are to blame for the impasse.

Jackson called the union’s demand for more preparation time “a last-minute grab to take away precious instructional time.”

“There is no justifiable reason that kids should be prevented from going back into class tomorrow because we refused to reduce the length of the school day or the length of the school year” she said.

Adding preparation time has been among teachers’ demands since negotiations toward a new contract began months ago. But as they prepared to strike and finally set up picket lines on Oct. 17, union officials and teachers more often spoke about reducing the size of classes and adding staff, including librarians, social workers and nurses.

Under the 2012 deal that ended the last major teachers’ strike in the city, teachers surrendered some paid preparation time.

They now want 30 minutes restored for elementary school teachers, who were guaranteed at least 15 minutes at the beginning of the school day under the previous contract that expired this summer. The union argues that teachers need that time to prepare lessons and say it’s unfair to expect educators to do that work unpaid outside of school hours.

“One of the great things about collective bargaining is that it gives the parties a chance to really figure out what’s working and what isn’t working,” said Robert Bruno, a professor of labor and employment at the University of Illinois Chicago. “So they agree to a contract, live with it for awhile and then say this isn’t working the way we thought it would, or here are the unintended consequences.”

In a 2017 analysis of teachers’ labor contracts, the National Council on Teacher Quality found teachers in large school districts typically get 45 minutes per day of planning time.

Some of the contracts also specify the amount of time teachers have to collaborate with colleagues.

The district has reached a tentative agreement with a separate union representing thousands of school support staff.
