 The Chicago Teachers Union's contract expires today amid months of negotiations between the city and teacher demands, hundreds of them that includes higher pay for teachers and staff, smaller class sizes, and that the city pay for affordable housing. In a district that faces a $391 million deficit, in the event of a stalemate, teachers likely wouldn't strike until after the start of the school year as they did in 2019. Though this time, CTU also has an ally, Mayor Brandon Johnson, who previously worked for the union.
