We have some PD happening here. I teach high school. When you start teaching in most places in the US, they consider you a new teacher for at least the first 3, if not 5, years. This is because a large percentage of teachers who leave the profession do so during that time period. In my district, teachers who are within their first 3 years have extra assistance available to them.
As additional background, this is my 3rd year teaching, so I am still new. Better than I was!! But still new. I have been at the same school from the start.
A new-to-our-school teacher began this year. We'll call him Tom. This is also his third year teaching. He has shunned all help available to him because "he knows what he's doing." Except he doesn't. His content is solid, but his classroom management is atrocious. I know because three (3!) different people have talked to me about it, wondering if there is any way I can work it into a conversation with him because no one else seems to be able to get through. (Tom and I hit it off at the start of the year, but our conversations have fizzled; these people thought we were still close enough that I could do this.)
Issues include: Students constantly on their cell phones. Students walking around the classroom, "hanging out" when they are supposed to be seated doing work. Students freely using profanities. Students generally talking the entire period, even when Tom is teaching, so that work just doesn't get done by anyone. None of these offenses are met with consequences, so of course, they keep happening.
Tom is so focused on having the students "work together" (an admirable goal!) that he has neglected to enforce basic classroom rules so that students respect him and each other. One of his supervisors suggested that he seat the students in traditional rows, instead of groups, because that can substantially help teachers who are struggling with classroom management. Students can't work together, but they also can't get distracted by each other and it's easier to keep everyone on task. He was horrified. They have to be in groups!
My first year, I desperately wanted my students to be in groups. But I quickly learned that I didn't have the classroom management skills to handle it. This year, all but one of my classes are in groups. That one? The kids are rowdy, and I don't have the classroom management skills yet to handle it. Because I'M STILL NEW. Just like Tom.
The principal is the one who gets the final say if someone is hired back. The 3 people (aside from myself) who know how bad it is are the support system. However, they all report to the principal, and word will get back to her eventually. There are already rumors that Tom's contract won't be renewed. But he still maintains his indifferent/know-it-all attitude whenever someone tries to help.
