There are two discursive frameworks concerning ideology in Australian industrial relations. In many disciplines concerned with aspects of industrial relations, including political science, law and history, it is the traditional political ideologies of the industrial era which take centre stage: liberalism (classical, social and neoliberalism), socialism (Marxism, social democracy and labourism) and conservatism. By contrast, ideological issues in the discipline of employment relations are chiefly addressed in terms of Fox’s three analytical perspectives: unitarism, pluralism and radicalism. The disjunction between these parallel discourses goes largely unnoted in the literature of the relevant disciplines, which all tend to proceed using their own preferred approach without making reference to the other. This article critically explores the relationship between these two discourses and investigates the broader implications that the existence of the two different discursive traditions has for the analysis of industrial relations phenomena in Australia.
