I will preface this by saying I do not have kids and therefore my last interaction with teachers was when I was at school. I'm not going to let my teenage years cloud my judgement.
I have recently taken on a job that involves visiting schools (think cleaning supervisor, but not) I spend a couple of hours walking round with the team, talking about challenges, reviewing paperwork and doing a general checks. I don't have to interact with the teaching staff at all (thank god). But I find them so rude. They think nothing of just butting in mid conversation, no "sorry, I can see your talking, could I just ask X a question" they just start talking. They stare with a frown constantly and consistently. They don't thank you or the children for holding doors open for them. And they never smile back if you smile at them...
It takes me back to being at school all those years ago and now I wonder if it wasn't just me hating the place. I wonder if the teachers were all like that too.
This isn't an isolated incident. I travel to many schools and they are all the same...
