1. My assistant was this person's official mentor. I also attempted to mentor this person (they were not only a fist year teacher, but we also going through an alternative certification program)
2. The band hall is two doors down. I could literally see and hear the craziness going on
3. My assistant and I alternate duty days right outside the band hall every morning.
4. I have band members in theatre classes
5. While I am not the "official" department head for elective, my assistant and I are the go to people for the department (especially the fine arts). We know everything that is going on because the admin wants us to know what is going on
6. I serve on multiple committees where I would be privy to the details
7. I'm actually involved in my school
I too am busy (region band, fall concert, pep rallies, sectionals, morning rehearsals, meetings, various committees, etc). Yet, I still find time to be a part of my school and know what is going on that might affect my band members and my class.
I was reading all of this last night at home and I have to wonder, how do you have time to get involved with all of this and document all of this and why? Are you the department head for fine arts? If so, that answers my question. If not, why? I get that this person is an incompetent, unprofessional teacher but, why would you get so deeply involved in all of this if you are not the department head? I have no assistant and personally just don't have the time to follow another teacher around to worry about their classes and duties. IMO, that's why we have a principal and that's why he gets paid more than me. I'm just curious because you are pretty detailed in this thread.
