Last year was my first year teaching. I came in mid-year and into one of the most challenging group of kids the school had. That being said, I was going to be placed into a co-teaching classroom. I was looking forward to this because I figured I would have someone who knew what they were doing and it would be nice to not feel alone and completely lost. Well, that positivity did little to make the situation better. This woman turned into a bully. I am a very easy-going guy and I don't like to tell people what to do. This woman would constantly be on her cell-phone, told me she was making purchases on Amazon (while I was giving direct instruction) on her school computer, would constantly leave the classroom whenever she wanted. Now, here's the thing. I came in with the idea that we would do things 50/50. And I asked how we would work out doing lesson plans and whatnot. She told me, "you're the core teacher, you do them. I don't do that." And I was fine with this! I figured that's how things were. So I started doing them on my own. She then went to the principal (who she was high school friends with) and told him that I was controlling and she was extremely unhappy. She would also tell the kids that I was controlling. I was NEVER controlling. I just knew her personality and didn't want to tell her "okay, now go up and teach the lesson!" I told her I loved it when she would take over because the kids enjoyed it and it gave me a break. But she would rarely do that. I wanted her to be comfortable with the content and not feel thrown to the wolves. One day to fix the situation, I told her (Again, trying to fix the situation) "I want this to be a great situation for both of us and I want us both to be really happy, so before I make these lesson plans, what would you like to do for next week? What activities, etc. would you be interested in working on with the kids?" Her response? "I don't know! I don't know the standards." In a really mean way. When we moved into a new classroom, she wanted all the kids' desks away from her desk because she had "sensitive information" as the ESE teacher that she didn't want them near. And I get this, I truly do. Except the kids were all bunched up by my desk (which did NOT bother me), and because of this they were angled far away from the whiteboard so many of them could barely see it and many of them had vision problems. I asked to meet with administration so we could all have a sit-down and get things in order because I truly wanted things to improve. Well, administration decided that sitting down together was not the right thing to do and this was my situation through the end of the year. I am now out of this school and into a much better situation. But I am extremely scared that I will find myself in a similar situation this year if I'm placed with a co-teacher. Does anyone have ANY suggestions for what I can do to prevent situations like this?
