We have something in our bylaws about "if a board member does not come to 2 consecutive meetings without notifying the president about not being able to be there- they will be removed off the board." But nothing about removing for not doing their duty.
Remember, this is a volunteer position- no paycheck-- I think I would have a board meeting with the person you are having problems with and discuss the issues-- maybe there's an underlying problem... personal problem-- not sure what position they hold and what they are not doing -- so it's a little harder to give advice-- but possibly letting the person know that you think they are not fulfilling their duties and is there anything you could do to help them might be the jolt that person needs-- maybe they don't even realize they aren't doing what they are supposed to... Give a few more details-- might have better advice. Good luck!
wasz--you need to check you bylaws to see what provisions you have in them for that sort of an action. If there are none stipulated then you probably need to come up with some sort of plan on how you want to set the standard for future events where folks are not living up to what they've stated they would do. It is an emotional issue certainly, and needs to be put in place in writing and as objectively as possible. In our bylaws it states that if an issue is so aggregious that a member must be removed they must have the recommendation made by 3 members of the PTO separately in writing. The individual is then informed of the proposal in writing and given a period of time to respond. Then the issue is brought before the general membership for a vote and the vote is taken.
I must say that doing something like that will be devisive and may cause more difficulties that you have by working around someone in the position, especially this late in the year.
If your bylaws don't have anything addressing the removal of an individual, you should convene a group to come up with those proposals so that you have an appropriate procedure in place. That is exactly what I did after reading some things on this board my first year and now feel comfortable that if the issue arises, there is at least an approach that seems fair and has been voted upon by the membership as the appropriate course of action.
