CPS and the teachers union have been at odds over pay and other benefits since their contract expired in June of 2015. 

“If I had to make a prediction, I’d say look for a strike sometime in October,” DiSalvo said. 

DiSalvo said that CPS will likely need to be bailed out by the rest of Illinois’ taxpayers since the city currently needs more than $1 billion annually to slow the growth of its own pension debt.

The cash-strapped school district closed 54 schools in 2013, less than a year after a teachers strike.
