Reliance upon industrial tribunals to resolve industrial disputes in Western Australia has changed significantly over the last 20 years and it is now set to change significantly again. Mediation is the key feature of the Employment Dispute Resolution Act 2008 (WA) (EDR Act) which was passed in June 2008 by the WA Parliament. It provides a framework for resolving any question, dispute or difficulty that arises out of, or in the course of employment in Western Australia quite separately from the framework under the Industrial Relations Act 1979 (WA) (IR Act). With its emphasis on mediation, it was a timely piece of legislation in the context of the 9th National Mediation Conference in Perth in September 2008 with its theme of ‘transforming the landscape’.
