Ooohh, this is a blood-boiler! The classroom layout is down to the teacher. If the teaching assistants have an issue with it I would have no problem with them telling me because they may well have noticed something I haven't thought of. However, changing it without talking to me when I have spent time moving things around would make me fume! Are you sure they know <u>you</u> moved the classroom around? Sometimes the cleaners shampoo the carpet in my classroom during the holidays and the caretaker puts the room back as best as he can remember it. Could they have thought this had happened and put it back the way they thought you wanted? Are you sure it was the TAs who moved it? Otherwise, you're going to have to have a full and frank discussion!
