Chicago and its charter schools avoided a strike after reaching an agreement early this morning. The contract addresses pension contributions, an 8 hour workday, and a maximum class size of 32 students. If class sizes breach that 32 student cap, teachers will now receive compensation. Additionally, the charter network has agreed to continue to pay for most of its teachers’ pension contributions, a practice that will not be applied to new employees.
