This article describes the complex temporal context of interactions between correctional officers (COs) and prisoners. Based on qualitative fieldwork within three French prisons, the results show an inequality of temporality between both groups in everyday life. The prison organization is seen as a model of reactivity, with COs reacting and adapting constantly to prisoners’ demands. Inmates often complain about the amount of time it takes to get a response to their request (e.g. cell change, appointment with a doctor, visiting room, etc.). Although COs are required to fulfil theirs tasks promptly. How do these two groups with different temporality live with each other? How COs deal with prisoners’ demands in a context of overpopulated prisons? These are some of the issues raised in this article that lead to a better understanding of life in prison.
