I reject every time I think the meeting is not a good use of my time. I always give a reason why I'm rejecting and sometimes that will be challenged but more often and not I don't attend the meeting and people don't get to upset.

A lot of the time people who are booking meetings will request attendance from anyone and everyone who may have a remote link to the agenda, they don't put any thought into whether the meeting will actually be useful to everyone they invite. Another problem is that people, usually project managers, will book meetings at the drop of a hat when a quick two minute chat at someone's desk would suffice - a lot of middle-managers have nothing to do other than attend meetings and they suck everyone else in with them.

I'd rather be as much as a ghost as possible in the environment lest I get more shit-work to do. Nothing, I set a world record in Temple Run from all the training I've received at these meetings.

Haha. Well, thanks for the honest answer. Having never been in that environment, I can't say what I'd do. =)
