This thesis is about the provision of social work services in the New Zealand workplace. A central line of argument is taken which proposes that the workplace, which up to now has been neglected as a site for social work practice, can become an important site for the provision of services. The development of a comprehensive model for occupational social work is the central feature of this thesis. Following the development of the model it is field tested in a case study involving a large employer. Located in the context of the development of New Zealand industrial relations, this thesis reviews the objections which have been raised when social workers become involved with a profit making organisation. Future possibilities for a specialised field of practice are proposed, making this thesis an early contribution to an analysis of the social work role in this setting.
