As an attendee at a meeting, its your job to :
✿ Arrive on time, even a few minutes before.
✿ Introduce yourself to anyone new before the meeting starts.
✿Turn off your cell phone completely.
✿ Bring all the proper materials connected with the subject to the meeting.
✿ Do not interrupt - ever. Wait your turn.
✿ Raise your hand, informally, when you want to say something wait to catch the leader's eye, and wait for a signal to begin.
✿ Do not bring food to the meeting. It is rude to eat to in front of others when the meeting does not call for a meal.
✿Remember to congratulate a coworker who made a fine presentation to the room. A quick four word email will do it: " Nice job today Erich !
