Law firms sometimes take the view that if a Partner has a strong following but is a difficult personality they can live with the personality because the financial return more than compensates for the problems the person may cause.
According to Harvard Business School one toxic employee costs the business as much as two superstars can make.
The message. Avoid toxic Partners. Regardless of their following they will cost you more than they make you.
How does hiring a toxic employee compare to hiring a superstar? Minor and Housman found that one toxic employee wipes out the gains for more than two superstars. In fact, a superstar, defined as the top 1% of workers in terms of productivity, adds about $5,000 per year to the company’s profit, while a toxic worker costs about $12,000 per year. The real difference could even be greater if you factor in other potential costs, such as the spread of the toxicity, litigation fees, lower employee morale, and upset customers.
