I often tell people if my manager and I think alike, one of us is unnecessary. And that means the potential for conflict.
Conflict is a term I associate with a negative connotation. But, differing ideas and opinions are extremely important in a business. How does one know if they have a strong idea, if no one challenges it.
Of course challenging a superior must be based on a relationship of trust, but building a team with strong leadership will establish that trust and enable team members to work together in a healthy and positive way. And also have systems in place to handle situations that could escalate if not handle correctly.
I have been in a position of conflict many times with a member or members of my team. Sometimes they were wrong, and many times I was wrong. Strong teams can handle the bumps in the road and will actually come out the other side stronger.
