We all know that toxic employees are a drag on the organization. In this HBR article I learned just how big that drag is. Superstars (top 1% most productive employees) each contribute $5,000 to the bottom line.
Meanwhile, each toxic employee costs the organization $12,000. That means it takes more than two superstars to make up for one problem employee.
If you believe the math, where you should put your immediate attention becomes obvious.
