Negotiation is a method of settling differences and reaching agreements without arguments. It involves understanding each side's position and seeking mutual benefit and fairness. Preparation, discussion, clarifying goals, and finding a win-win outcome are key stages of negotiation. Successful negotiation requires understanding attitudes, gathering knowledge on the issues, and using strong interpersonal skills like listening, communication, and problem solving. The overall goal is to resolve conflicts through cooperation rather than resentment or dissatisfaction.
