Project Summary: Discussion: Mediation in the Workplace Mediation is an effective, collaborative, conflict resolution method that, although informal and voluntary, still requires the agreement and commitment to the process from both parties. HR professionals can use mediation as a tool to promote more effective communications and understanding among employees in the workplace. As the mediator, the HR professional can facilitate the process, keep the lines of communication open, and assist the parties with arriving at a mutually satisfying solution to a workplace disagreement or dispute.
