Dr. Grier shares his 10 rules below.

In his book Dr. Grier talks at length about each rule, tells you what he learned, and offers his insights on how you can use the rules to help you and your colleagues survive the narcissist in your midst.

Rule Number One: do not attempt to reason with a narcissist.

• A narcissist is not open to other people's ideas.
• Every situation must make the narcissist feel better about himself if he is to accept the outcome. This is unlikely -- let's be honest and admit that it's impossible -- and therefore conflict is inevitable.

Rule Number Two: never confront a narcissist about his misconduct when the two of you are alone.

• To break through the barrier that the narcissist erects around himself, confrontation should always be done in groups of at least three (the narcissist plus two), and larger settings such as meetings are even better.
• If the manager chooses a private setting for confronting the narcissist, he should be prepared for failure and counterattacks.

Rule Number Three: set boundaries.

• Disrespect and antagonism do not have to be tolerated.
• The narcissist will do everything he can to make professional disagreements personal.

Rule Number Four: let no negative action go unchallenged.

• The difficulty with Rule Number Four is that by the time you discover that the narcissist has conducted himself unprofessionally or unethically, a significant period of time may have already passed.

Rule Number Five: normal management techniques do not work.

• Throw out the book on management techniques, and break out the book on leadership.
• Zero tolerance should be the rule when dealing with a narcissist, and removal from the workplace should be management's first instinct.

Rule Number Six: keep a record.

• Coworkers would be wise to keep a "bulletized" record of dates and incidents when they find themselves in conflict with a narcissist.

Rule Number Seven: expect criticism.

• There is no more savage critic than a narcissist who has decided he does not like you.

Rule Number Eight: if the narcissist does not like you, do not worry -- it is not about you.

• If you find yourself helpless to find middle ground with the narcissist, it is useful to realize that this is the narcissist in full flower.

Rule Number Nine: it is OK to feel relief, even joy, when you and the narcissist finally part company.

• When I finally ended two years of dealing with my narcissistic coworker, I celebrated the end of a difficult and personally harmful relationship.

Rule Number Ten: pick up the pieces and don't look back.

• Because of your experience, the real fun and enjoyment and appreciation for a healthy work environment has just begun.
