theodp writes: 'Now that the strike is over and teachers are back in school,' writes Ben Joravsky in the Chicago Reader, 'it's a good time to visit the story of David Corral, the UNO charter school teacher summarily fired after he notified officials of a 'mock rape' in the boys' locker room.' A favorite of City Hall and recipient of a $98 million state grant, UNO is headed by Chicago Mayor Rahm Emanuel ally Juan Rangel. School officials reportedly praised Corral at first for reporting a potential incident of sexual abuse to the police (would that Penn State administrators had done the same), but within several days flip-flopped and told gym teacher Corral he was being terminated for lax supervision of the locker rooms. For his part, Corral believes he was used as a 'scapegoat' to send a message to the staff. 'I believe Rangel fired me because the police came to school and took those kids in handcuffs,' says Corral. 'That was an embarrassment-someone had to pay.' As a nonunion, at-will employee, Corral's contract stipulated that he could be fired 'at any time for any legal reason or for no reason, with or without prior notice.' Joravsky concludes: 'As he hands out more contracts to nonunion charters, Mayor Emanuel also vows to replace 'bad' teachers with 'good' ones. Let's hope he knows which one's which.'
