I have a similar problem. We have certain rules we’re supposed to follow. While it annoys me that other teachers don’t clean the classrooms when they finish, that’s all it is–an annoyance.
However, one rule is that we are not supposed to speak Hebrew in the lessons. I do my best to follow that (not so difficult since my Hebrew is pretty poor). But I sometimes lose students to teachers who are willing to speak Hebrew. Since I get paid only for the lessons I teach, following the rules is costing me parnassah.
I’ve brought it up to the supervisor and to her boss. I’m waiting to see what happens.
