Being late to meetings, family outings, or any other event is unacceptable. In preparing my presentation for this year's IBM Pulse08 Conference in Orlando, FL I used a quote in one of my slides from Tom Peters that says, "Don’t over-schedule - Running late is inexcusable at any level of seniority; it is the ultimate mark of self-importance mixed with contempt."
Being consistently late for meetings is unacceptable, rude, and tells others that you are more important than them. If you don't have time to attend all the meetings you are invited to then decline them. Don't accept a meeting invitation and show up late.
You are never too important or too busy to be on time. You own your schedule and it is your job to manage it properly.
DON'T BE LATE!
