One of the costliest mistakes senior leaders make is hiring people who are just like them. The problem with this mistake is that it often results in senior leadership teams rewarding behaviors that are similar to their behaviors and criticizing behaviors that are often needed in the workplace.

It's human nature to more easily get along with some people than others. But, when that tendency translates into our hiring practices it can have a negative impact on an organization's culture.

Senior leaders influence organizational culture more than any other factor, and, if all senior leaders are thinking alike....well, then, no one is thinking at all.
