In this article, we discuss temporal work and temporal politics situated between groups with different temporal orientations, arguing that attention needs to be paid to covert and unarticulated silent politics during temporal work. Drawing on a case study of a management consultancy project to redesign public health care, we explain how unarticulated temporal interests and orientations shape the construction of problems, which, in turn, legitimate tasks and time frames. We also show how task and time frames are temporarily fixed and imposed through boundary objects, and the way these may then be reinterpreted and co-opted to deflect pressure to change. Thus, we argue, unarticulated, covert and political temporal inter-dynamics produce expedient provisional temporal settlements, which resolve conflict in the short term, while perpetuating it in the longer run.
