Contributing to a Foucauldian perspective on 'discursive resistance', this paper theorizes how part-time workers struggle to construct a valid position in the rhetorical interplay between norm-strengthening arguments and norm-contesting counter-arguments. It is thereby suggested that both the reproductive and the subversive forces of resistance may very well coexist within the everyday manoeuvres of world-making. The analysis of these rhetorical interplays in 21 interviews shows how arguments and counter-arguments produce full-time work as the dominant discourse versus part-time work as a legitimate alternative to it. Analysing in detail the effects of four rhetorical interplays, this study shows that, while two of them leave unchallenged the basic assumptions of the dominant full-time discourse and hence tend instead to reify the dominant discourse, two other interplays succeed in contesting the dominant discourse and establishing part-time work as a valid alternative. The authors argue that the two competing dynamics of challenging and reifying the dominant are not mutually exclusive, but do in fact coexist.
