Increasing proportions of the work-force in many industrial countries have become marginal, or more loosely attached, to the labour market. Full-time employment in large public and private corporations has decreased. Partial or temporary unemployment, partial or temporary self-employment, and small familybased enterprises have become more common. The size of the informal, untaxed and uncontrolled economic sector is considerable and probably increasing. These trends are clearly discernible in many modern economies, including Australia’s.
