Party-directed mediation (PDM) is an emerging mediation approach particularly suited for disputes between co-workers, colleagues or peers, especially deep-seated interpersonal conflict, multicultural or multiethnic disputes. The mediator listens to each party separately in a pre-caucus or pre-mediation before ever bringing them into a joint session. Part of the pre-caucus also includes coaching and role plays. The idea is that the parties learn how to converse directly with their adversary in the joint session. Some unique challenges arise when organizational disputes involve supervisors and subordinates. The negotiated performance appraisal (NPA) is a tool for improving communication between supervisors and subordinates and is particularly useful as an alternate mediation model because it preserves the hierarchical power of supervisors while encouraging dialogue and dealing with differences in opinion.
