It's almost as if she has posted to create controversy on purpose, surely she knows what the reaction will be putting something like that on a public forum

if you don't want people's opinions then don't have a public account and post adverts, share all the details of your children's lives.
Surely the safeguarding lead at her school must be stressing every time she posts.
Interesting that she has been taken out of class and just teaches PE. Not that there is anything wrong with that but school budgets are so so tight I find it hard to believe that they would willingly pay a fully qualified teacher just to teach PE, in 99.9% of primary schools a sports coach teaches PE and they are (wrongly in my opinion) paid an absolute pittance. Surely they would only remove a full time (expensive) class teacher and allow her to teach solely PE, replacing her with another expensive class teacher, if she just wasn't getting the results, wasn't up to scratch and the children weren't making sufficient progress.
Would be very interested to see what the parents, pupils and other staff (particularly SLT) think to her account
