An examination of the interaction between child care and parent workplace stress. The study follows ethnically and socioeconomically diverse parents, and randomly samples their behaviors and attitudes to measure the effects of child care disruptions as they occur. Hypotheses include: (1) Parents using workplace-site child care experience fewer negative consequences as a result of child care; (2) Women are more likely to experience the effects of child care problems spilling over and affecting outcomes at work than are men; and (3) Low-income families experience more negative outcomes as a result of child care problems.
