[영문]Based on a longitudinal case study of the work offered by a Swedish sheltered work organization that can be regarded as 'dirty', in the sense that it stigmatizes those people that do it, in this paper I analyze how 'dirty work' can be seen as an important yet so far neglected source of the social construction of disability. Specifically, the aim of the paper is to suggest how an individual can become a 'disabled person' by doing dirty work. By working on 'tainted tasks' people (irrespective of their mental or physical condition) may come to be regarded and even officially labeled as 'disabled', i.e. incapacitated and impaired for any 'normal' and 'clean' character of work.
