In post-industrial societies labour market de-regulation, the growth of non-standard work schedules and shifting gender patterns in the paid labour market are re-shaping family care practices and work/family balance. In this article, the work/family arrangements and practices of nurses are compared with those of builders in Melbourne, Australia. The concept of family time economies is used to explore the intersections of work time and family time. Some change in traditional gender divisions of labour was evident in the nurses’ families but in the builders’ families more traditional gender specialization was displayed. The article contends that the organization of work time shapes the temporal structures of family life. Gendered patterns of employment in sex-segregated industries intersect with gendered family care practices in complicated and sometimes contradictory ways, but gendered differences at work and at home have a significant influence on how time for paid work and care is distributed between parents.
