I teach secondary, and have a Yr 11 tutor group. My co-tutor, 2 days each week, is a cover supervisor, who is well known and well liked. She is in her mid 20s, and is beautiful. She is curvy with a real hourglass figure, and dresses well for her shape and age.
Yesterday morning was her first session with my tutor group - I was doing one-to-one sessions in a different room. She mentioned afterwards that some of the students had very openly talked to her about the size of her bum. One of the girls had told her that her bum looked "huge" in the dress she was wearing. She laughed it off with the students, told them that she'd rather they didn't make personal comments, but told me afterwards that she had been upset. This morning, the girl who had made the "huge bum" comment saw her and started singing "I love big butts and I cannot lie" Obviously I dealt with it, but the girl insisted that she was paying a compliment. The teacher later told me that the same girl had patted her (ie the teacher's) bottom the previous day and had said "hi big bum". If this was a Yr 11 boy, then I would imagine the school would be down on him like a ton of bricks, but the girl doing this seems to think she's doing nothing wrong. I am not my colleague's line manager, and whilst I have been sympathetic and supportive, can't really do much more. Should I speak to her line manager about it, or leave it for her to deal with?
