If the behavior continues and you are truly bothered, begin by separating yourself from those individuals. Find like-minded colleagues to work with and (respectfully) avoid the ones that offend your sensibilities.

You mentioned you are new to teaching (1st year?). Once the school year begins, you are going to have plenty of other work and issues to distract you.

Good luck!

Hopefully this first year you wont damage too many kids while you are learning. Your job is not to police the other teachers. I taught for 17 years and have been a principal for the past 5. I call tell you every year I learn something new. As a teacher I was totally clueless when I first entered the classroom. Ironically, I thought (like you) I knew more then everyone else. Leave supervision of teachers to your administrators. Everyone will appreciate it. This is not the advise you wanted, but if you listen, you will get along much better this year.

Don’t be discouraged, its all about your kids anyways.

I work with some toxic teachers, too. I just steer clear, and I do not associate with them (as politely as possible). Change happens very slowly, but perhaps others will follow by your example.
