Daycare troubles

Ma

We started at a daycare center for my 2 and 3 year old. They are in different classes because we asked that they be separated. We LOVE my daughters class. However, we are very unhappy with my sons teachers and the overall environment of his room. There is one boy who is very aggressive (hits other kids, runs around the room, throws toys, and will break supplies). I know the teachers are stressed because they are constantly calling for help and usually have to have him removed, however they then treat the parents and students rudely. In addition my son is picking up these behaviors and we can’t break him of them. I have a feeling this boy will be dismissed from the daycare because he is not meeting the handbook guidelines but I don’t know for certain. Should we stick it out or ask for my son to be moved to the other class?
