I'm on two different committees and both have issues with people putting their names forward to join and then never having the time to get involved or even attend committee meetings. The Chair of one Committee has just had to ask a couple of people to step down as they haven't come to any meetings this year. One was okay about it, but the other is going around muttering about us being 'cliquey', 'not wanting anyone with a different view'. This simply isn't true. But any time we suggest dates for a meeting she's working late, or has to bring her kids swimming or collect her husband from somewhere. Fair enough, she's busy but then why take up a place on a committee. She's also never free to help out with any activities;. Basically she's no help but still has to be emailed about everything, giving a vote on things etc. So she's costing us time.
AIBU to think you should have the sense to only join a Committee if you can genuinely engage and contribute?
