A teacher at our school got sent to prison for sexually abusing his children. He was a nasty creepy fucker who used to tell the boys in our class to stand under the stairs or lie on the floor so they could look up girl's skirts
Not one person was surprised about his conviction, just felt sorry for his kids.
That wasn't even the biggest drama at our school, he was such a pervy prick we were just glad he'd gone.
Several of our teachers met at school, and at least 1 couple were originally married to other people. There were also a couple of others having affairs (quite openly). Loads of kids used to smoke at breaktime as there was no supervision (also this was the 1980s) but that wasn't drama, just the way it was. Come to that some of our teachers used to smoke in class. It was a different time
I then changed schools for 6th form to an all girls school. The big dramas there were - mainly the number of teachers/ former teachers in relationships with pupils, one of the teachers had a full on mental breakdown in the carpark at lunchtime one day and was vandalising cars (before getting taken away by the MH team) however the one that provoked most outrage from the teachers was when someone tippexed something blasphemous on the wall; we had several whole school assemblies as that was taken v seriously (As you can gather it was a very 'good' school with no behaviour issues given the teaching staff felt that was the worst thing a pupil had ever done!)
