You’ve heard of  the 80/20 rule from Pareto, an Italian economist who posited that 80% of the wealth is held by 20% of the people. Expand that concept and you get 80% of the sales is made by 20% of the sales force or 80% of the purchases are made by 20% of the customers. Here is an important concept for those who manage companies: 80% of HR problems are caused by 20% of employees.

Because people have enduring patterns of behavior those with a personality disorder rarely change unless they hit rock bottom and recognize that the way they interact has devastating effects on their careers and their relationships with others. In brief, those with personality disorders rarely change…and managers are always trying to change them thus they waste 80% of their people management time on 20% who are rarely going to help the company progress.   

Blaming, excuse making, and refusing responsibility for personal behavior mark a individual with a personality disorder. Other characteristics may include:

• Poor frustration tolerance
• Impulse control problems
• The inability to delay gratification
• Poor self-esteem that may be masked by grandiose thinking or a masochistic effort to please others
• Problems getting along with others
• Obstinacy and inflexibility
• Creating chaos
• Inducing frustration in others
• Poor job performance
• Lack of empathy
• Self absorption
• Behavior blind spots that others can clearly see
• A “poor me” attitude
• Alcohol or drug abuse
• Multiple divorces
• Poor relationships with family members
