Is your meeting your calling it My advice would be to do the following. Let people know the exact agenda. Let them know the start time and the exact ending time, then you need to start on time and end on time even if some people are late if you do this, you will build your reputation. As someone who is a productive person who doesn't waste time, the more you burnish your own reputation for not wasting people's time, the more you are perceived as an actual productive person.
