Let's say you are the scheduler of a department-wide meeting (that is too long, drawn out, and could be eliminated if you got up off your ass a couple of times a day and asked people the questions you ask when you have us all in the same room waiting for our turns to talk...again, that is a story for later). Let's also say you have scheduled that meeting to take place at 10am on Tuesdays and Thursdays.
If you cannot be on time for your own meeting consistently, if you are late for it at least 2 out of 3 times, schedule it for 10:30.
On that 1 day out of 3 that you are on time, do not walk around the cubicles squealing "meeting! it's meeting time!" in your most condescending voice. We do not like the meetings, we do not like being condescended.
