This is going to sound awful.
A girl joined DDS class in September. DD has some special needs and is quite vulnerable and DD immediately had some issues with this girl, disrupting her in class, ordering DD about and being aggressive with her if she didn't do what she said or give up the piece of equipment DD had and she wanted immediately.
She disrupted DDS learning for weeks (GCSE age) and nothing was done until DD got in trouble for not putting enough effort into a piece of work and also had a sensory overload.
DD was moved away from her only after I complained and the girl who sat next to her wasn't as much of a push over as dd. The troubled girl didn't like this and immediately tried to fight her. She was expelled from her old school for fighting according to the girl herself.
Today during mock exams she was disrupting again and did the finger across the throat motion and then physically went at a child when they left the classroom.
Various children have complained but the teacher has told the girls that she has had a tough life and they should give her a break .
My child has had a tough time too and I understand the child needs support but aibu to think that when she is being violent the kids shouldn't just be being told to give her a break?
