Their analysis revealed that the average benefit of firing toxic workers is around four times greater than that of adding a good employee to the organization. Remarkably, even if companies could attract a superstar employee— defined as someone in the top 1 percent of job performance— getting rid of a toxic worker would be twice as beneficial financially. And this benefit is without considering any likely collateral damage, such as litigation, regulatory penalties, and decreases in employee morale. If the ripple effect for bad behaviors is as strong for employees, one can only imagine how big it is for leaders, who affect many more people in the organization.
