while at school my sons teach got upset with him not following directions so she left him outside the classroom alone then when she got tired of seeing his face through the door she forcefully pulls him into the classroom. She then puts him back out in the hall crying and bleeding because she left 2 scratches on his arm and he walks off to the nurse alone and not telling anyone. On the same day in after-school care and non-english speaking assistant is trying to help him with his homework which he refused to do because he can't understand her. she proceeds to the the after-school care teacher about this. She dismisses everyone to go and play so my son goes outside. She pushes his head back twice which leads to him falling on the ground she tells someone to get a chair and she pick him up and throws him in the chair. I would just like to know what can I do?
