Think about these equations:
Healthy people + wrong role = conflict
Unhealthy people + wrong role = conflict
Unhealthy people + right role = conflict
Healthy people + right role = effectiveness
These equations illustrate three truths. First, it explains why conflict is so prevalent within organizations. Second, it illustrates the importance of hiring healthy individuals who have good EQ and understand how to relate to others in healthy ways. Third, it reminds us that even healthy people when they are in the wrong role can create conflict with people around them.
The keys to avoiding conflict are having healthy individuals in a role that is consistent with their wiring. When this is compromised, conflict is likely to result.
Unhealthy individuals, especially in leadership roles create conflict regularly. It can be a result of poor or non-existent people skills, inability to resolve differences or conflict, poor self awareness, hubris and a quest for power or any number of EQ (Emotional Intelligence) issues that leaves a wake of relational issues behind them.
When hiring, pay close attention to EQ skills and deficits. If you miss something and find that an individual leaves relational issues in their wake, get them coaching and if that does not work, move them to a position where they will not cause conflict. Don't allow an individual to create ongoing issues within your organization. It is counter productive, will hurt your return on mission and is unfair to staff who are impacted.
What about conflict with healthy individuals who are cast in the wrong role? This is conflict based in the skill set of the individual and not in their Emotional Intelligence. For instance, you can have a leader who does not know how to delegate, who micromanages, who changes their minds on a regular basis, who has no definable strategy and we could go on. This is not because they are unhealthy people. It is because they are in a job that is inconsistent with their wiring.
Getting the right people into the right role is absolutely critical to building a healthy organization. If you need to make adjustments for this to happen - do it. The alternative of conflict is a trade off you don't want to make.
