Source: (2000) In Mediation in Context, ed. Marian Liebmann, 155-165. With an introduction by Marian Liebmann. London: Jessica Kingsley Publishers.With respect to the United Kingdom, Noonan observes that the current approach of the Advisory, Conciliation and Arbitration Service (ACAS) to employment dispute resolution is rooted in employer-trade union interactions in the nineteenth century. ACAS exists to offer neutral, third party services to prevent and resolve workplace disputes. In this chapter Noonan details how ACAS provides such services. With this in mind, and using certain case examples, he presents definitions and discussions of matters such as collective and individual conciliation, arbitration, and advisory mediation.
