Keep meetings to the scheduled amount of time.
Don't force the next group to stand in the hallway outside the conferrence room waiting for you and your group to finish.
Eat lunch in the cafeteria or break room. Avoid eating smelly food at your desk.
Avoid wearing perfume or cologne at work.
Respect your co-worker's property (and company property).
Don't yell or scream at others. Compassion and empathy will serve you much better to earn respect.
Don't copy bad office behaviors.
Stay calm and don't get emotional or angry. A sympathetic comment is the best way to direct a coworker toward better behavior.
