I am on long term supply and struggling with a class. Most kids are ok but there are three children that misbehave. I follow school policy and it has no effect. One constantly shouts and sets the other off. The other tries to hit them. I obviously intervene but it's awful. Children are taken to calm down but I'm left. I've no TA support and the strategies in place don't work. I really don't want to go back but I feel guilty for letting the school down and the agency. I've no other income so am letting my husband down. I feel trapped.
