Abstract

The New South Wales union movement embraced the principles of heritage and conservationism in the 1970s through the imposing of “green bans” – a strategy wherein union members refused to work on construction projects that were a threat to the state’s natural or built environment. Led by radicals like Builders Labourers’ Federation leader Jack Mundey, the green bans were seen in several sectors as a departure from the traditional “Old Left” priorities of securing workers’ wages and conditions. Rather than a hard shift towards radicalism, this article proposes that the green bans were instead reflective of an already existing conservationist tradition in the New South Wales union movement. This reinterpretation is predicated on a content analysis of extant historical material such as contemporaneous news articles, personal memoirs, transcripts of political speeches and archival documents related to the policing of left-wing activism in the 1960s and 1970s. The results show that an existing tradition of engagement with a broad spectrum of social issues in the New South Wales union movement predates the emergence of the New Left, including the commitment to environmental justice principles that underpinned the green bans.
