10 surefire ways to tick off your co-workers

2. Answering cell phone calls during meetings

A surefire way to aggravate people is to consistently respond to calls, e-mails and pagers when in conversation with others. This sends a message that they are less important than the caller. Let the calls go and return them when your current conversation is over. If you are expecting an urgent call, alert those present. They will appreciate that you value their time and that you stay focused on matters at hand.
