Oh yeah I'm pretty sure parents with a grudge would go trawling facebook for ammo - look at some of the attitudes on here of people who believe they own the very soul of their kids' teachers. Newsflash - my soul is my own between the hours of 3.30pm and 8.45 am the following morning and 24 hours at weekends. If you don't like that idea - tough. We don't get paid enough for our souls to come as part of the deal.
In fact if you've got trouble coming to terms with the shocking realisation that teachers are people too, with lives outside of school (surely it's only the kids who believe we live in the classroom cupboards) - then the fact that teachers drink, smoke, occasionally say a rudey swear word and even have sex will probably blow your mind. Then again, we've had threads on here complaining that teachers have DARED to get pregnant and cause inconvenience so nothing surprises me anymore.
The only thing that was screwed up was that they'd not got their privacy settings locked down tight enough - but considering FB keeps changing the bloody things and making it maximum pain in the arse to get set up - I can partially understand it.
I'd actually rather that the people teaching kids had a clue about the real world to be honest. I remember being taught sex ed by a nun and thinking "what the hell do you know?"
I tow the line of the law, I exercise some sense of awareness (ie I don't stroll down the street outside school chugging away on a ciggie - not that I would anyway since I quit), I make sure that I keep work and private life separate - if that's not enough (and cheesy hen nights are NOT illegal yet... although I'd gladly make them so) then no one would want to work in education anyway!
