If a coworker doesn't acknowledge you as you pass in the hallway, it may simply mean he or she is racing to get to the bathroom. Know what's provoking you. If you've had a fight with your spouse or you're under the gun on a project, don't take it out on a coworker. Don't get angry just because someone else is. Be aware of your anger signals.
Anger reveals itself physically through a racing pulse, shortness of breath, or pacing.
Take a breather. Find ways to temper your temper before it flares. Do breathing exercises, take a walk, or even do busy work. Talk to a friend. If it's unwise to direct your anger at the source, confide in a friend.
