My child came home from school upset and distress after a teaching assistant covered his mouth and nose with their hand and telling my child to shut up.... My child was extremely upset. I complained to themed who told me they would investigate. After school the head then told me the ta had not lost their temper and that it was done in jest. I am completely disgusted the ta has got away with such behavior. The head belittled me for complaining and dismissed the whole incident as a joke
