This paper is a critique of the tradition of sociological writing which has emphasized the ability of occupations organized on the professional principle to gain for their members an occupational monopoly and a position in the division of labour which provides them with autonomy to determine occupational tasks and functions. It is argued that theories which seek to account for the conditions which provide the framework for successful resistance to rationalization and codification in professional work have not adequately articulated the concept of power. The theoretical discourse on professional and managerial power has therefore tended, with few exceptions, to locate the determination and exercise of power as though it were a zero sum commodity deriving from social relations of organizations. Theories predicting the emergence of professional rather than mangerial forms of control therefore have little explanatory ability other man for a particular mode of rationality within a limiting theoretical framework. This analysis represents an attempt to propose a mediation between structuralist theories of power and organization and those theoretical reflections on the professions which locate the determination of occupational authority in a broader matrix of social processes.
