It's a fine line, giving thanks to people who are helping out (and we all know how EASY it is to get people to help
), and looking like you're finding ways to abuse your position. Giving the volunteers who helped a break, I can't see a problem. Giving the teachers a break...well, that's a little much. Sure they work hard (well, most of them). But the money raised IS for the kids. I don't think asking them to pay what the "regular" people pay is asking too much. They are paid employees after all!
I have a problem with giving board members perks. They're supposed to be there because they want to volunteer their time. If something like free camp for their kid is going to be the deciding factor if they take the office or not says to me their heart isn't in the right place, and that they probably won't do the best they can. I could be wrong, but it doesn't look good. Giving perks like that tends to have a snowball affect, and before you know it positions ARE being abused, whether it's intentional or not.
Our school district is by no means poverty-stricken, so I can't understand what that is like. I would hope though, that in there somewhere are the people who would love to put unknown and untapped skills to use. Maybe it's just a matter of finding the right message to get to the parents that people need to step up to the plate. Maybe you have to lay it on the line that without officers, there can't be a PTO, so if they want good things for their kids they can't depend on others this time around.
I had sympathy for both parties in this round of threads, because I'm usually the one seen as the "squeaky wheel," but I'm also the president of a group, and I see how sometimes "squeaky wheels" are just that, squeaky, and not the well-intentioned folks they want to be.
Good luck to you, and I hope all works out OK for your school!
