Adversarial relationships typically lead to distributive (win–lose) negotiations, where each party seeks maximum gain at the other’s expense. Trust is low, information is withheld, and concessions are hard-fought. While it can deliver short-term wins, it risks damaging long-term relationships and may reduce overall value. Collaborative, integrative approaches are more sustainable, but adversarial conditions often prevent them. CIPS highlights the importance of recognising relationship dynamics before selecting negotiation style, as forcing integrative approaches in adversarial contexts may be unrealistic.
