This paper aims to propose an analysis of dirty work. It is argued that this kind of work may contribute to an enlargement of the Social Psychology of Work agenda. In methodological terms, firstly the paper recasts and refreshes the meaning of dirty work such as originally proposed by Chicago School members. Next, a reconceptualization of dirty work is carried out, based on the frame of reference developed in the work clinics field. The paper argues that dirty work should not be confused with other kinds of work studied by Social Psychology. It holds that dirty work refers only to those activities in which one can’t identify an instituted sense of collective work. Finally, the paper discusses theoretical challenges in studying dirty work, making suggestions for researchers interested in this subject.
