Is it Ridiculous Expectations of Teachers Week on Mumsnet?!
Are we really expecting them to not have boobs, emergencies OR friends/relationships now?!!
It sounds like the teacher is either boffing the Mum or is friends with her. And frankly, so what if he is?!!
Christ, my DS's primary head teacher and his family used to meet up with one of my School Mum friends and their kids for a week of camping in France every year. You know, because FRIENDS!
Not unethical AT ALL.
At no point during either teacher training or working in the role did I ever hear of this as a problem.
At the very most, the teacher could divulge to the school if he enters into a romantic relationship with the Mum but if they are friends he has no obligation to tell school at all.
Why would DS dump his GF over this? And what exactly are you fretting about him being 'mixed up in'?
HUGE overreaction here, OP.
