Am nomadic in my school. Teach in all three multi-storey buildings. Nightmare for having to carry things and be organised. JUST about manage that. Struggle with those who dislike having an "invading" teacher and make it hard as possible - not moving own classes out promptly, hanging around faffing while I am in there, making comments about how much they need the room, etc. I am all charm and politeness, but inside feel awkward and unhappy. What would you do if this were an enduring problem for you?
