This paper explores issues of social and multiple identity and their implications for equality law and practice. The paper considers three principal dilemmas – passing, groupism and the limitations of participatory justice as a political strategy for the achievement of equality. The objective is to contribute a ‘thick’ understanding of issues of identity and identification with which to inform and situate the development of the UK's ‘single equality approach’. The paper argues that the negotiations of identity required of members of minority groups is a form of work.
