The models or approaches used by individuals or groups in negotiation situations reflect a person’s orientation towards achieving their goals in comparison with their interest in cooperating with the other party. Researchers of management and organizational behavior such as Thomas and Kilmann (1974) have developed a model that explains that negotiation revolves around two main axes: the degree to which a person cares about his or her personal interests and the degree to which he or she is interested in maintaining and cooperating with the other party. As a result of this interaction, four main styles arise: cooperation, competition, compromise and avoidance.
