In recent years the Finance Sector Union has pursued a range of strategies which rely on the incorporation of customers into its campaigns. These strategies extend from the employment of a discourse of shared worker and customer concerns in its communications with union members and the public through to the development of alliances with consumer and community groups. While easy to advance in an industry where customer disillusionment and frustration is widespread, these appeals for solidarity and the formation of alliances are not unproblematic. In the light of lessons drawn from US literature on community campaigning and the experiences of other Australian unions, this article explores the limitations and potential of union strategies that seek to incorporate the customer and evaluates the alliances formed between the Finance Sector Union and community groups.
