Patricia, I can certainly understand the head banging you're doing--I think we ALL have had days like that, even the ones who have great teachers.
We also have a few teachers who just don't get it--PTO is all of us at the school. We have the rule this year--if a teacher hasn't joined PTO,their wishes from the wish tree we have are not filled by PTO--the wishes are on the tree & if a parent chooses to fill that wish--great, otherwise, it stays there. We have die cut flowers at the bottom of the tree listing the names of those teachers/assistants/staff who ARE members.
One thing we did with our carnivals( to get more active participation from teachers) was to let each teacher decide the activity THEY wanted to do and any money raised by them was accounted in a "savings acct." by the PTO treasurer. That money was there for the teacher to buy items for their classroom. The way it works, the teacher makes the purchase with her own funds and then is reimbursed from her fund when she submits the receipts. We did it that way so there was no chance of the money going toward non-class related items. Some have even used the money for end of year pizza parties for the kids rather than supplies and the kids love it. This system allowed teachers who haven't joined PTO to raise money for what they want.
Our PTO was set up to include one teacher on the Exec board. She is our liason and it has worked well for us.
Maybe it's childish to say "that's the way it is and if you haven't contributed to finding a solution, tough"--I've actually said it myself, so don't feel bad, but sometimes, you just HAVE to get it off your chest. Our PTO board also is on the SIT( School Improvement Team) and this has helped A LOT in helping us know what the teachers'/school's concerns are. Two of the committees are concerned with communication and school climate. We're working hard to make our school one that has the "feel" that makes you WANT to be there and getting along with all those personalities is key.SIT is a Federally mandated group, so you might want to check it out at your school.
We encourage teacher attendence at functions by having drawings for things--gift certificates to the local school supply store are popular.We started out with sparce attendence, now, it's closer to 50%.
Hope some of my long winded reply helps.
