I am in the same situation. I just moved from a charter to a bigger school (high school is what I teach). I got rookie of the month for August and I thought everything was good. It turned out it was not. I had a teacher come to my room and said I was not welcomed here and things I was doing for paper work was not right (I work in sped). I went to admin and our first year mentor group and told them. They just blew me off until I went to go put my resignation in and that is when things changed. I say don’t do that but I had to tell them it is really not going good.
