Hi I am active in my sons school and the PTA (we call it PTO). I have been President, Vice and Secretary over the years. I have also chaired commitees for school as well as the non-profit I work for. I think there is no generic answer to your question about what to expect, all group dynamics are different as the people in the groups are all different. Expect to work hard, expect that there are those who “do” and those who “don’t”. Many times it is the same people on alot of the committes, PTA etc…because they are the ones who volunteer their time. There will be some who will do all they can to help you and some who will do as little as they can get away with.Not everyone has time to volunteer, some do have the time but don’t and there are those who hardly have a minute to spare but will help you in other ways… printing, making copies, emailing etc…accept any help in you can get. I think if you realize that the work load is not evenly distributed on many of these endeavors you’ll be fine.
Before you jump in this weekend with all the great ideas you have to share I would let her know you are interested in the teen Health commitee and ask what kind of work/events etc… the committee has done before . Your new ideas may not be so fresh after all and may have been done to death , unless of course this is a new committee. Usually a commitee that is already established has a goal…what exactly is the goal for this committee in regards to teen health/safety? That would be good to know. I would wait to share your ideas until you have that information and then I would likely wait to share my ideas with my actual commitee members as opposed with the person recruiting volunteers. kudos to you for volunteering.
