Constructive conflict management is hard on problems and easier on the people involved. Real problems get addressed. Clarifying the problem, focusing on the issues, and identifying each party's interests gets to the heart of a conflict. Quality solutions are identified. Solutions that you and the other parties involved identify, create, and select typically lead to more satisfactory solutions, a greater commitment to follow through, and in general, more durable agreements.
Workplace relationships are more likely to remain intact.
You can return your attention to your job. Unresolved or poorly managed conflict can become a major distraction and often consumes considerable personal energy.
