A federal court judge put on hold a previous order for Chicago Public Schools to retroactively change its teacher layoff process with the Chicago Teachers Union. The ruling comes as the latest in an ongoing battle between the district and the teacher’s union, which alleges that when CPS laid off hundreds of teachers over the summer due to budgetary constraints, district administrators did not abide by seniority and instead relied on other factors, such as unsatisfactory evaluation ratings and overstaffing projections, to make its decision. The court had previously ordered for CPS to reinstate the terminated teachers and provide back pay, however since CPS is appealing the ruling, a judge agreed to stay the order until the appeal is decided.
