Significant changes in state policy took place from 1996 to 2007. The 1996 Workplace Relations Act (Cth) sought to shift the industrial system away from a collectivist approach, where unions and the Australian Industrial Relations Commission (AIRC) had strong roles, to a more decentralized system of individual bargaining between employers and employees. The Act diminished the traditional role of the AIRC by placing the responsibility of resolving disputes at the enterprise level. This allowed mediation to be used to resolve industrial relations disputes instead of traditional conciliation.
