Dd (18) is in her 2nd year of sixth form. Last year when she was 17, an issue arose with a male teacher whose behaviour was highlighted as inappropriate with female pupils, one of whom was my daughter. He had been taking selfies on their phones and sending them links to inappropriate things on social media (I don't know the details as my daughter wasn't involved in the latter, but he did use her phone to take weird selfies). Anyway, at the time I spoke with the school's safeguarding lead who assured me that they were dealing with it and it was referred to the police. The teacher was not suspended and my daughter told me that, while she still saw him occasionally around the school, he'd been advised by the safeguarding lead in no uncertain terms not to have any contact with her.
Today my daughter called me at work upset, saying she had seen him and he had asked her to "meet him in a classroom for a chat". She made and excuse and scarpered with her friend. Later in one of her classes she said she saw him hanging around outside the door looking in, which she assumed was for her. She later left her lesson and said she got herself out of the school as quickly as possible to avoid him, and came home.
I'm really angry that she's being made to feel this way, and although it doesn't seem he's done anything that constitutes a criminal offence and is clearly still employed, I do not think he should be lurking around my daughter making her feel this way.
Before I call the school with all guns blazing, how would you handle this? AIBU to be angry, or do I need to let my now adult daughter handle this? She's only very recently turned 18 if that's relevant.
