A continuing challenge for the teaching profession is, therefore, that as teachers enter their professional employment in schools, they are likely to be treated as novices in need of support from more knowledgeable colleagues.
It also doesn't help that for the first three years of your career, you have to be in a "mentor" program. You have to jump through so many extra hoops and check a bunch of boxes with a veteran teacher. You really don't have a voice the first few years of your teaching career. And some mentor teachers are better than others. I've had one treated me as her equal, another who micromanaged my classroom and insisted I do everything how she did, and the last one who simply told me, "I told the district I didn't even want to be a mentor." It's rough out there for new teachers those first few years. And whether or not you'll even get quality "knowledgeable colleagues" to collaborate with is a shot in the dark.
