Many countries, however, have not addressed the issue of union security agreements. Neither Indonesian nor Thai labor law addresses the issue, and in both countries collective bargaining, union administrative procedures, and dues collection are so weak that the union security issues rarely arise. In Australia, the legal status of union security agreements has varied widely across each state and the national government and over time. Australian labor law does not explicitly regulate union security agreements. However, various forms of the union security agreement have been favored at one time or another by each state, territory, or the national government, effectively regulating the favored type of union security agreement and disadvantaging its other forms.
