What does the work environment look like when working as a social worker in a hospital or school.?

I want to work with children so I am deciding if I want to be a social worker for a hospital or school. But I also wonder how a day to day would look like. I have talked with the few social workers I know but most of them work for the state rather then the field I want to go to though it might be the same I still want to know in what ways its different and what could be similar with work load, hours and more.
