...you're leaving because behaviour at your current school is SO bad?
This is a non-teaching role, but I'm still up against the rudeness/disrespect/hooligan behaviour of students I work with or who pass through the area where I'm based.
I've been there seven years, so I guess I'm looking for new surroundings anyway, but the new job wouldn't hold any particular new challenges so I don't think I can say that's the reason.
Any ideas?!
