Has anyone ever had a problem with a previous teacher coming into their classroom "at-will?" The previous teacher came into my class and made plans with my "aide" to come back, not even consulting with me. The aide acts funny when the old teacher comes into the class, too. The previous teacher has no children who attend the school, no reason to be there, and is very rude to me, trying to tell me what to do with the class. I don't mind advice, but not from pushy people who act like I don't know what I'm doing (she rolls her eyes if I say something about what I am going to do). Should I talk to my principal about this? I get that she was this "wonderful teacher who was there for 1000 years," but I need room to grow and fit in at my school and I can't do that with her hanging around trying to make me feel inferior. What to do?
