CTU President Karen Lewis made the allegations in a Friday morning press release detailing a complaint filed by the union to the Illinois Educational Labor Relations Board over the ongoing battle between the union and City Hall.

“A couple of weeks ago I sat down with the mayor in his office to talk about how to roll out a longer school year and what components would go into making it a better school year for our students but he did not want to have that conversation,” said Lewis. “When I explained to him that a longer school day should not be used for warehousing or babysitting our youth he exploded, used profanity, pointed his finger in my face and yelled. At that point the conversation was over — soon thereafter we found ourselves subject to a full-scale propaganda war over a moot point.”

Emanuel was expected to be asked about Lewis’ claims at a school event this morning.
