"Interpersonal skills are extremely important for managers dealing with a wide variety of personalities. All of your employees will be different—each will have his or her own way of thinking and operating. Your challenge is to be able to help them overcome these differences and mesh as a team. "

This is a exert that I found in Businessweek.com.  Managers are the ones that lead the many and need to be the ones that show the many how things are done.  Leading by example and being interpersonal are two of the main factors of being a "good" manager. 

Do you have the right managers in place to make your business run flawlessly?
