Most people don't like personal conflict, it's just natural for us to avoid that, as our primitive instincts tell us that personal conflict can lead to personal injury.

Thankfully in the modern office context however, personal injury is unlikely but conflict is still present: especially for those in leadership positions.

Conflict within the team, conflict with vendors, conflict with customers, conflict with the market opposition: if you hate conflict, you will hate being a leader as all of that and more is coming your way.

However, a leader who avoids that conflict is avoiding responsibility, and that is untenable. The job of a leader is to untangle internal conflicts within their team, while confidently meeting external conflicts head-on.

A leader who constantly avoids conflict will lose all credibility with their team.  And remember: the first step in winning a fight is acknowledging you are in a fight in the first place, rather than burying your head in the sand.
