A federal judge has ordered Chicago Public Schools to "rescind" the layoffs of 700 tenured teachers who were let go earlier this year. It's a win for the Chicago Teachers Union, which filed the lawsuit on the grounds that the layoffs were handled improperly. CPS is considering an appeal. Of the 749 tenured teachers who were initially fired, CPS says 417 have been rehired already.

UPDATE (10/6): Chicago Public Schools plans to appeal the ruling, arguing that they had a process in place to help the fired teachers find new jobs. The district estimates that rehiring all tenured teachers could cost CPS about $30 million.
