The U.S. industrial relations system has undergone a historic transformation over the past three decades. One of the most significant features of that transformation has been the dramatic rise of alternative dispute resolution (ADR) as a means of addressing workplace conflict. ADR can be defined as the use of arbitration, mediation, and other third- party techniques instead of litigation to resolve workplace disputes. In the view of some experts, the rapid diffusion of ADR in employment relations, especially in the non-union sector, has represented nothing less than a revolution in dispute resolution. The ADR revolution has spread to many other types of disputes, including family, consumer, construction, and financial disputes. In many ways, transferring the resolution of workplace disputes from public to private forums constitutes the de facto privatization of the American system of justice.
