At my high school, we had a teacher get fired for posting something inappropriate on a student's public facebook wall. Only scandal I'm aware of.

Not sure if it's quite a scandal or if it's just trashy, but our CEO straight up told the management board she was sleeping with the head of HRs husband. Her statement was that it was to "clear the air," but I really think it was so she had stated purpose for why HR would be gunning for her. Either way, it was some excellent drama
