Abstract: | The gendered division of household labor is more multifaceted than the allocation of paid work and domestic work. People also engage in volunteer work and informal support. I investigate the applicability of household labor allocation theories—specifically the time constraints, economic, and “doing gender” perspectives—to all unpaid work. I analyze the 1997 Australian Time Use Survey diaries of 1,797 married couples using logistic, ordinary least squares, and seemingly unrelated regressions. Analyses show that volunteer work and support work are substantial expenditures associated with paid work and housework, but they do not create a “third shift.” Volunteer work and support work are part of the gendered household labor allocation process determined, in part, by time constraints and by gender. |
