Thanks Rose, I ended up deciding to remain in office through the end of the school year but informed the board that I would not return. Things are really complicated by the fact that he has close personal friendships with some of the other board members, who share my concerns but don't want to rock the boat. Since I informed him of my decision he has reacted very childishly, so it's going to be a long few months! The sad thing is walking away from all of my hard work, because of someone who will likely destroy the organization and lead to it being dismantled, but you can't make others do what they don't want to.
Sounds like you are in a difficult situation and you worry about what you do and how it will affect others is really something.
A couple of things. Is there anyone else on the board? Can you and whoever remains ask this new president to a meeting and raise these concerns? If the president refuses, can you reach out to the principal and ask for some help -- perhaps the principal could sit in on a board meeting and try to help your remaining team at least look at the issues that have come up and are making it difficult for your board to function. It sounds like this new president doesn't really get how a parent group board is supposed to work.
If you feel that this situation is beyond repair, then you need to take care of yourself and do what is best for you. It will be March in just two days. Do you want to hang in there until elections at the end of the school year and then step down? It sounds like you've worked really hard on behalf of your group and your school, but now you need need to do what works for you.
I'm really having a hard time reconciling my feeling of being unable to work with our recently elected PTA president and the fact that I would be really causing a huge problem for my board if I was to resign.
I am the treasurer, who has spent the last year cleaning up prior treasurers mistakes, I handle spirit wear, I am heavily involved in our upcoming spring carnival, but our new president is just impossible to work with. His ego is completely out of control because he brought in a couple of corporate donations (literally, soup for about 30 teachers and candy for about half of our students at the holidays, that's it) and he just has no regard for the rules when it comes to things like budget, the payment authorization process, things we are and are not allowed to do. The guy is a loose canon, I feel like it's only a matter of time before he does or says something that is going to have some really serious consequences.
Now he has turned around and upset one of our board members to the point where she has resigned, and he is unwilling to do anything to resolve it. For me it's the final straw, I can't trust him, I don't want to be associated with him, I just want out. I just don't know how to go about it without making things really difficult for everyone else.
