Dirty work - Laurie Taylor explores the invisible labour we choose not to see. The writer and sociologist, Eyal Press, considers the morally dubious, even dangerous jobs, which sustain modern society but which are concealed from view, from the prison guards who patrol the wards of America's most violent and abusive prisons to the migrants who work in industrial slaughterhouses. What are the ethical, as well as physical costs of doing this kind of labour? Why do those individuals carry the stigma and shame of doing 'dirty work', rather than the society which condones it? Ellie Johnson, Research Fellow in the School for Policy Studies at the University of Bristol, discusses the treatment of older people in two English residential care homes, sketching out the workers' attitudes and practices concerning hygiene and bodily waste and the ways in which they do, or don't, offer dignity and respect to those receiving care. Is the mistreatment of older people simply an outcome of a deeply inequitable market for care provision or can it also tell us something about the way in which marginalised groups, such as elderly and disabled people, can be dehumanised?
