DS is in year 8 and his regular English teacher wasn't there today so the head of English taught them. Since its hot she opened a fire door which leads out to metal steps. DS had a headache and asked to stand outside and the teacher refused. Apparently he kept asking and the teacher said she wasn't letting him out. She told him if he was really ill to go to the office so be did and I've had to collect him. He now admits he doesn't feel ill but he did have a headache which he feels would have been fine if he'd been allowed out! Aibu? The teacher shouldn't have kept him in should she?
