> What about volunteer charity workers? Is it OK for them to just not show up whenever, just because they aren’t paid?

I have some friends whose profession is running charities (i.e. they actually get paid). Volunteers not showing up is exactly what happens, all the time. And my friends expect it, plan for it, because the volunteer is not getting paid to be there. Without that tangible incentive, a volunteer time competes for all the other intangibles competing for time (e.g. "I'm tired", "the kids need something", "friends are going to do something fun at the same time"). They build it into planning: some percent of the people who signed up aren't going to show up...if the weather bad, a bigger percent aren't going to show up. And so on.

They don't get all ranty or judgmental about it, they're just smart enough accept that reality and to plan for that eventuality. Just like anyone using an open source project without paying for it should be.
