The Public Private Call
Coworkers don't need to know how your date went last night, so tone down your phone conversations.
E-mail Vents
Build in a cool-off period before pressing "send" on a rant. Don't e-mail anything you wouldn't want to see on the company bulletin board.
Mute Button Fail
Conference calls should not be punctuated by the sound of crunching Doritos. That's what the "mute" button is for.
Bad Hygiene
Mix in a toothbrush or some mouthwash after lunch. Please.
Good Hygiene Gone Wrong
Flossing or gargling in the office is tacky. Use the restroom.
Oversharing
"Reply" and "Reply to all" are separate buttons for a reason. Don't spam people with needless correspondence.
Facebook Familiarity
Best not to dis the company with your status updates, whether or not you have colleagues among your online friends.
Oral Fixation
Chew with your mouth closed, just like mom said. If you must chew gum, be discreet.
Ringtone Mania
You think the theme from Shaft is a cool ringtone. You are correct, but the whole office need not be reminded of your pop-culture expertise.
TMI
In briefings, share only details that need to be shared; if they want to know every incremental step, they'll ask.
Working Blue
The workplace isn't a frat house. Dispense with the f-bombs and sexual innuendos -- even with the same sex.
