I've been subjected to meetings without chairs. The problem is, there are some people for whom standing is not much of a burden and they go on and on. So, I was forced to stand there at this daily mandatory meeting while people talked about stuff that was not relevant to the work I was doing for 30 minutes.

If you want to have a standing meeting, that's fine, and it can be good-- but I think the rule should be no meetings can ever be mandatory, and anyone can leave any meeting at anytime. If the person calling the meeting doesn't have an agenda compelling enough to get people to show up, then the meeting shouldn't happen anyway.

I will no longer stand (literally) for mandatory meetings. (Which is, just another of the daily things I am thankful for about being my own boss.)
