Based on mixed method, this paper deals with the different ways to conciliate job career and private life for academic people who are strongly confronted to spatial mobility. Academic career and mobility influence stages of conjugal and familial development, so that the construction of a stable couple is more difficult and fertility is postponed. Nevertheless, some recurrent forms of spatial mobility, such as commuting, may constitute a conjugal arrangement to conciliate job career and family life. In everyday life, these arrangements point to gendered differences on family management. Academic mobile males delegate children care and housework to their non-mobile spouse. On the contrary, academic mobile females take charge, at the same time, of domestic management and job career. This double task leads some of these women to reject mobility that is necessary to an academic career, and so implicitly to stop this career.
