What exactly is a buddy teacher? I guess things have changed since I was in school.
I remember punishments like standing in the corner or writing something like "I will not talk in class" several hundred times for minor issues. Anything above that resulted in the teacher paddling your ass. If the issue was so serious the teacher feared he or she would be tempted to beat you to death you were sent to the principle who either beat your ass or suspended you.
My guess is that these are students with a variety of problems, and there is a "buddy teacher" back-up, maybe handling issues from 2 or 4 classes as they arise, in between classes and the principal or vice principal.
I agree with "Person #s" that it's odd that the principal thought the 5 who reported the "barber" should have been sent to the "buddy room".
On a very different tack, it was very unwise and unprofessional for "demtenjeep" to post about this incident in a public place. It would not take super-hacker grade Internet skills to figure out where she lives and teaches, and possibly figure out who some of her students are (the skills to learn all that are well beyond me, but I don't think it would take the degree of skills necessary to hack into the DNC's email).
My fixed rule, dating back nearly 20 years, has been that I do not speak of my employer in public places like Internet discussion sites or FB; and infrequently and in limited ways about past employers (even the several that no longer exist).
