1. Don't ignore people in the elevator. Make eye contact and at least smile even if you don't talk on an everyday basis.

2. When you make personal phone calls, keep it down. Better yet, step outside.

3. If you take anything from anyone's desk while they are not there, make sure you return it or at least leave a note saying that you took it.

4. Knock before entering someone's office, even if the door is open.

5. If you're sick, even a little bit– stay home.
