Interference with the performance of my duties.

civil service office games 101. you need a mentor in game playing.
sadly none of the things you are being subjected to have anything whatsoever to do with teaching children their 3R's. if the bad teacher acting out is AA and you are not,it going to be much much harder to correct, if not and if he is white male, you got a nice juicy target for EEOC assuming you are female.
again you need a mentor.

I agree with many of the comments. I've had a fellow teacher either intentionally or unintentionally misconstrue emails and go to the principal about me. I was in my 3rd year of teaching, close to tenure, and really concerned that these remarks would cost me my job. I went to my supervisor, and I joined NEA. If you haven't joined a teacher's association, please do. In the end, I didn't have to fight for my job but it is a good resource to have on your side. In your case, I would go to your direct supervisor (if you haven't already) and tell him/her what is going on. You should make an appointment with the principal, but don't go alone. Bring your supervisor, your building rep (if a member of NEA), and any witnesses that can vouch for you. Do continue documentation. Documentation is your friend. I know it is easier to wait for it to go away, but the principal will believe who is talking to him. If you don't say anything, he will believe the other guy. In my situation, when I came out fighting and standing up for me, the other guy backed down. It is harder to spout lies when the truth comes out. I hope this works out. I know it is not a fun situation. Good luck.
