Son is in year 11. When he got home from school he said he feels sick. And when he was at school he felt sick and had stomach ache and at break he vomited. He said the teacher knew but they sent him to a classroom which was also a first aid room and he staying in there for 3rd lesson after break which was pe anyway. But for 4th lesson they sent him to class and just told the teacher to keep an eye on him. Then at lunch he went back to the first aid room to stay in (it's also a lunchtime club for children who don't like the hall) and he told them he felt sick and they told him to eat something (he didnt) and that there was only 1 lesson until home time.
No idea why they didn't call me to pick him up.
