My PTA days are over but the 'same faces all the time' was always a bit self-fulfilling.
Yes to this. Someone said to me (on joining a new school) "I like to help out at events but I won't be in the PTA" which puzzled me, as I thought the PTA was for all parents, and you were automatically in it, and if you helped out that was that.
But of course they meant they weren't in the "inner circle". I personally don't like to hear people moan about how "it's always the same people every time" because you know what, so what if it is? If you have time and are happy to volunteer it, does it matter it's you and X others again? If you don't want to do it, don't volunteer at all. Your contribution shouldn't be based on anyone else's presence, just like anything in life.
I have been on both sides, working practically full time and having more flexible arrangements, and if you want to volunteer there is always something to be done that isn't physically manning the ticket booth at the school gate.You don't get "extra" credit in karma for reading with the Yr1 kids over and above sorting a great raffle prize or sponsorship - it all helps to take the pressure off teachers and the school and benefits the children.
Equally, if you don't choose to volunteer for anything but you spend your cash generously, that's great. Or if you never turn up to the events with your kids fair enough too.
What you can't do is moan that you don't like what's on offer if you're not willing to be part of the solution one way or another.
I do it because I see the value in it: I like what it means for the children, both in terms of the fun events that they like, and the money it raises to enrich their education. I also do it because I was brought up to get involved (my parents spent a lot of time organising stuff like this when I was a kid too) and because I have the skills and the opportunity.
But I really don't care if anyone else can or can't, or think badly of them. If there are not enough volunteers things don't happen, and that would be the natural consequence - I am fairly good at policing my own boundaries on that and not committing to stuff because of pressure if it's not possible without burning with resentment.
