I think they have access to the files, not sure, because they have to pull them out and leave them on the T's desk for his appointments for the day. Like dr's files. But whether they get to sit down and read them, I'm not sure. The staff are bound by confidentiality. Same as I work in a school, and am not allowed to talk to anyone about anything I see in a student's file when we pull them out, add to them, and put them back.
