During summer school today, I was chatting with a colleague who split a contract (50/50) with another teacher last year. They both have young children at home and didn't want to work full-time. Anyway, my colleague was the AM teacher and another lady was the PM teacher. She said it was so incredibly difficult to share a classroom with someone else. They both had different views on classroom management and classroom arrangement. One wanted the classroom to look in pristine condition, while the other was pretty messy and not concerned with tidiness whatsoever. Additionally, one was relatively strict and no-nonsense; the other was super laid back and easy going. At the end of the conversation, my coworker said she's returning to full-time teaching in the fall. She said she's "much too controlling" to ever share a classroom with someone else. It got me thinking: Could I ever share a classroom with another teacher (even if we were never in the room at the same time)? Your thoughts?
