Abstract
New Labour's approach to partnership working in the United Kingdom has emphasized a technical rationalist approach to achieving partnership between social work and its partner agencies. While endeavoring to provide an organizational environment in which partnership can be successful, less focus has been given to addressing differences in professional cultures that are crucial for ensuring successful partnership working. This article argues for the importance of considering different professional identities, values and ethics within partnership arrangements. The developing research literature will be investigated to show how the absence of a serious engagement with different professional identities has hampered successful partnership working. It will suggest that by drawing on the work of Jürgen Habermas and his theory of communicative action that different professional identities can begin to be reconciled. It does not suggest that Habermas's approach is unproblematic and considers the critique of communicative action and its emphasis upon building consensus by Seyla Benhabib. What the article suggests is that communicative action and the ethics that underpin it point toward a possibility for ethical communication between different professional groups.
