In this paper I make an attempt to develop a conceptual framework to be use in a study of the body practices of knowledge workers. Following the distinction between physical labor and knowledge work the work of knowledge workers are mainly seen as involving the use of the mind while the use of the body is mainly associated with physical labor. However, in these research notes I want to argue that also in the work of knowledge workers the use of the body play an important part. Based on this argument I develop a framework for studying the embodiment of professional identity among knowledge workers. The framework has three perspectives: the competence perspective, the consumption perspective and the power perspective.
