The place of work and family in the schedules.

Summary This thesis analyzes, with the help of the French Time Use Surveys of 1985-86 and 1998-99, the temporal balance between work and family resulting from the latest social transformations: flexibilization of working hours, massive wage-earning of women and subsequent generalization of dual-working couples. After a novel description of the temporal forms of work, carried out with the help of a variant of the optimal matching methods, and of the social inequalities that run through them, family time and the gender inequalities that affect it are revealed. Finally, it is shown that the degree of synchrony of bi-active couples is linked to their social position: the best social positions correspond to the most fusional couples but also to those who are the least temporally invested with their children. The social inequalities with respect to work schedules partially counterbalance the gender inequalities observed in the family.
