Abstract:The classical view in the sociology of professions is rooted in Parsons' work. By using the term "profession," this view tries to distinguish a class of occupations that serves a specific function in society. As is well known, such a functional view in the sociology of professions came under attack in the 1970s, when professionalization processes were increasingly analysed in terms of interests and power. In this article, we have pointed out the theoretical and empirical relevance of a line of thought that emerged in the 1980s in the German-speaking academic world. It has revitalized a functional approach based on research into the interaction between professionals and their clients. The general idea that has emerged is that research into the microstructures of professional action could reveal a societal function that would explain the particular institutional features ascribed to professions.Keywords: Professionalization, functionalism, professional-client interaction, revised theory of professionalization, objective hermeneuticsThe sociology of professions witnessed major shifts that were deeply interwoven into the history of modern society itself. Previously, professions were of central importance in sociological thought, with Parsons (1968) considering them the most important single complex of modern society. Functionalism, which dominated sociology for most of the mid-20th century and was closely related to Parsons' work, referred to professions' functions in society in order to explain the traits that differentiated them from other occupations, for example, their autonomy in controlling their occupational performance. This view was largely replaced in the following decades by research into professional action, which focused on the question of how an outstanding and in some sense "professional" status would be achieved in a given field of action. To explain the creation of a professional status, not only careful and detailed studies of the realities of professional action were conducted. The described processes of professionalization were analysed chiefly in terms of interest and power (Macdonald, 1995). Thus, whereas the first approach was apt to justify the privileged status of professions in society, the latter questioned its legitimacy.Today, discussions about professions take place in a quite different constellation. Now, the sociology of professions has to deal with the epochal changes that accompany deep transformations in the system of occupations and the organization of work
