What is it like for a person to handle working with multiple personalities in a group?
Actually, I will correct that sentence. (to handle working with many people with different personalities)
Ahh -- that clarifies your question. I had assumed at first that you were talking about individuals -- each of whom had multiple personalities.
The leader of a group of diverse people draws upon the strengths of each individual. S/he seeks to avoid the weaknesses. And -- of course -- always treats everyone with respect and values their individuality.
