Throughout the 20th century, Australia has maintained a system of tribunals to make decisions about wage and non wage outcomes and to help resolve industrial disputes. Institutional forces affect the operation of the free market in order to improve labour market outcomes, such as guaranteeing minimum wages and conditions. The four institutional forces that affect labour markets are Governments, Trade Unions, Employer associations and Industrial Relations tribunal.
Trade unions represent groups of workers on a collective basis. The most important trade union is the Australian Council of Trade Unions (ACTU), which is the peak union body to which most unions are affiliated. Trade unions membership has declined substantially from the 1970’s with an average membership of 55% to just 23% in 2003. This is caused by the increase in casual and part time employment, growth in industries with low union membership such as retail and the decentralization of wage determination.
Employer associations represent business groups in similar industries in industrial relations matters. They seek wage moderation to maintain profitability. The head employer association is the Australian Chamber of Commerce and Industry.
At the federal level is the independently run Australian Industrial Relations Commission (AIRC). They establish and maintain the fair minimum rates of pay and conditions (award safety net system) for all workers. Award wage increases are determined by the AIRC annually after hearing submissions from the government, ACTU and unions. They apply the no disadvantage test to CA’s and AWA’s to make sure workers are better off than the underpinning
