Full-time working women’s activity gives rise to a variety of work-family life balance experiences. The type of child care is a source of organisational tension, both temporal and subjective, for both work and family life. The “subjective distancing” is undermined where there is intrusion of work into family life and of family life into work. It is difficult to quantify this mental workload of permanent conscious attention. It is relative, in the sense that its weight varies from one woman to another, and it varies at different points on the socio-professional trajectory. Mothers are often trapped, due to the weight of social roles. As a result, certain forms of “resistance” amplify the stresses of the work-family life balance.
