I’ve been playing with comparisons with my job and team woes
I am forever getting students complaining about other teachers (and I’m sure they complain about me elsewhere)
Sometimes it’s just venting
Sometimes there are legit gripes but there’s really no way to intervene to address issues
Very rarely there are issues that I will bring to admin’s attention but even then it would be hard for admin to take action at that moment
Almost always my response is that they can’t (shouldn’t) do something that hurts them in long run - like not doing assignments/studying only hurts the students. In fact I tell them that they probably should work harder for the teachers they don’t like
