Australian unions have adopted new organizing methods to rebuild and develop their organizations. This represents a change in direction from the commitment to partnership and tripartite planning that characterized the Accord period under the Labor governments of the 1980s and 1990s to a new focus on capacity building. A serious decline in union density along with shifts in the labour process has led unions to focus on recruiting and organizing new members. The vitality involved is tempered by a hostile legal climate that supports workplace flexibility, casualization, fragmentation and low-wage work, while curtailing the rights of unions to recruit and organize. This paper explores the common heritage between the new organizing and theories of popular education, radical history and social movement experience. The paper suggests that contemporary efforts to regenerate unions as assertive organizations that rely on developing and educating new activists and leaders can benefit from drawing on emancipatory traditions of popular education, radical history and community organizing, and in so doing avoid an uncritical adoption of what might become simply a new set of organizing techniques.
