Workers' compensation or workers' comp is a form of insurance providing wage replacement and medical benefits to employees injured in the course of employment in exchange for mandatory relinquishment of the employee's right to sue his or her employer for the tort of negligence. The trade-off between assured, limited coverage and lack of recourse outside the worker compensation system is known as "the compensation bargain.” One of the problems that the compensation bargain solved is the problem of employers becoming insolvent as a result of high damage awards. The system of collective liability was created to prevent that and thus to ensure security of compensation to the workers.

The Australian labour movement began in the early 19th century and since the late 19th century has included industrial and political wings. Trade unions in Australia may be organised on the basis of craft unionism, general unionism, or industrial unionism. Almost all unions in Australia are affiliated with the Australian Council of Trade Unions (ACTU), many of which have undergone a significant process of amalgamations, especially in the late 1980s and early 1990s. The leadership and membership of unions hold and have at other times held a wide range of political views, including socialist, democratic and right-wing views.
