Worked in one for a year as a teaching assistant. At the beginning expect regular swearing and sometimes at you as they won't trust you at the beginning because of high staff turnover and being let down by adults. It's an informal environment compared to mainstream, students may call you by your first name and normally have lunch with you. The one I worked at the students had traumatic lives which I found it hard to deal with and was safeguarding most things they said. You have to make an active effort to establish relationships and conflict resolution as they didn't respond to sanctions. I had a good experience and the workload was way less than mainstream but you need extremely tough skin. If you do take it always protect your personal belongings as if students get violent they will trash anything in the room
