I used to volunteer for stuff with the PTA. I don't anymore.
I used to attend meetings when I could. Don't bother with that either.
The reason being is the 'main' ones in the PTA walk around with a holier than thou attitude. Being overly nice and polite to everyone and then bitching about people behind their backs. I soon cottoned and and so thats not for me, I'm out.
All of these women think they are the absolute best and on one else gives as much as them to anything, and they give off this vibe that lets people know that. Including to others who are new to volunteering and would quite well ahve continued had they not been made to feel quite so inadequate at their first volunteering session. So most people now just can't be arsed with them. A few parents who used to volunteer don't for this reason.
Plus on more than one occasion you'd volunteer for something and you'd end up doing something else (much more shit) or they'd railroad you into staying longer than you agreed to, guilt trip you when you can't and it just becomes a pain in the arse. Many parents have realised its just easier to say no.
I know summer fairs and whatnot are nice for the DC, but honestly I wouldn't care less if they didn't happen. And if they do, fine - those who are 'better than everyone else' can now sort it out, those on the PTA who have managed to whole heartedly make every other parent feel like shit, even when they've been volunteering ffs.
Its a shame, I'd be involved way more if it was inclusive and not some group who think they run the world and everyone else is their minions.
Maybe others in the PTA at your school come across a bit like that op? not saying you are, but you can guarantee nearly all the women on our PTA have no clue they come across like this. They all think they are the best parents there (and unfortunately more often than not put peoples noses out of joint because of it). All fake smiles and ' soooo good to see you's.....' and then moaning because Barbara who volunteered at the school disco was too slow puring drinks, and 'oh my god, did you see her trying to fill the urn'.
