I am a very envolved parent too and I have to take some offence to some of the postings above. Who gave the right to ONE person to decide who can and cannot volunteer? I believe it is up to the school, its staff and its administration as to what will be tolerated. As far as thinking because someone is very involved makes them a bully, I think that is ludicrous. Unless you have real proff that they are "out to get you" then don't make such judgemental accusations. It is a big country and a big world, it would serve our children best if we set a good example and not judge, but be proactive and positive. Our school LOVES the help they get from positive involvment and when the envolement is not positive then they do something about it.

the types of activities that comprise relational bullying (as happens in some volunteer organizations, workplaces, etc) which is just one type of bullying (verbal, physical, are the other 2 major ones) include:
gossip, rumor, backstabbing, ostracizing, shunning, excluding another member ie thats how middle school girl cliques operate, as well as some adult cliques/groups or persons.
gossip ALONE does not necessarily equal bullying, but it is a very very large component when the practice is present. want more info go to bullyonline.org or read the books 'odd girl out', or 'mean girls all grown up'.
gossip is never productive. and yes, there are many bullies in the world, some are more obvious than others.

Gossip is simply not bullying, that is just crazy. Gossip is bad and tacky but not bullying. If gossip is bullying then the world is full of bullies and that just is not the case. Who has time to micromanage volunteers motives?

PTO = psychology takes over?
it (psych) is at the heart of most, if not all, human interaction. check out Daniel Goleman's book: Emotional Intelligence, and Blink, by Malcolm Gladwell. you will know all you need to know for PTO purposes, or at least, a start, and applies to all facets of life so its time well spent.

for the school- "Since this person is well liked amongst the teachers and the staff, then she must be doing good."

i couldnt disagree more. the cleverest bullies are the most beloved people (whether clergy, teachers, respected doctors etc etc etc). they are con artists. i do not suggest active volunteers are bullies, but IF a volunteer is at school for the purpose of self and not others, that is not good for anyone. you have to KNOW if the volunteer does any negative things, has ulteriour motives for being there so much (ie rumor mongering and gossiping about other volunteers is the single easiest and least detectable way to bully other parent volunteers). if there is no know DOCUMENTED ulteriour motive, then yuo should ignore difficult personalities and live and let live (and volunteer!!). they are part of life, teh difficult people

Fortheschool,
As a parent who has a hand in almost everything, I have tried to stay away from this post because I feel I am a bit biased.
If you ask me why I do it, it's because I want to know that I am doing everything in my power to make my children's school the best it can be.
If this person gets along well with everyone and gets people to join, then maybe you need to look at why you don't like her. It's ok not to like people just because, we all have those feeelings, but that isn't a good reason to try to force them to be uninvolved in something that they may feel is their legacy to their child.
May I suggest you go with the flow and try to make friends with this person-who seems to get along with people-and try to make your group and your school the best it can be. If you feel like they are taking all the jobs you want, then ask if you can do something this time as you think you would enjoy it or you would like to be more involved or because you see she already has so much on her plate. I have never been offended by someone asking to take over a responsibility. But please, don't ever ask a parent to be less involved in their child's life for your personal gain.
