A substantial number of adult children, both in dual-earner and single-parent families, are increasingly relying on grandchild care to bridge childcare gaps. Despite the growing trends of grandchild care and the prolonged participation of older Americans in the workforce, prior evidence over how time spent on grandchild care is associated with grandparents’ employment outcomes remains inconclusive. Considering unobserved (time-constant) heterogeneity is important for a better understanding of the association between grandchild care time and employment/work hours, because mixed findings in prior research may be attributed to omitted variables, such as preferences related to grandchild caregiving and work. Empirical research has not yet examined how grandchild care time influences family-to-work conflict and work-to-family conflict over time among employed grandparents. To examine these questions, this dissertation uses the Health and Retirement Study between 2004 and 2014 and employs fixed effects models to take into account unobserved heterogeneity and to address selection issues, and use a random effects model for family-to-work conflict.

Chapter two illustrates that considering class and employment informs us with further understanding of grandchild care time, while the effects of gender and race/ethnicity on the time allocated to grandchild care largely remain. Particularly, non-employed NH Black men with a high school diploma or less provide substantial grandchild care (500 hours or more over the two years; approximately 4.9 to 96 weekly hours), matching the level of care provided by non-employed NH Black women with the same education. Class is only linked to the time spent on grandchild care for employed NH White and Hispanic men. College-educated employed NH White men engage in a low level of grandchild care (1-99 hours over the two years; about 1 weekly hour), which is greater than that of employed NH White men with a high school diploma or less. Employed Hispanic men with some college education or more tend to provide an intermediate level of grandchild care more (100-499 hours over the two years; roughly 1 to 4.8 weekly hours), whereas devoting to substantial care less, compared to employed Hispanic men with a high school diploma or lower education. Employment status exclusively influences the time that NH White grandparents dedicate to grandchild care: Non-employed NH White women and men are more involved in substantial grandchild care compared to their employed counterparts. In contrast, no employment variations in grandchild care among NH Blacks and Hispanics may suggest that racial minority groups prioritize grandchild care regardless of their employment status.
Chapter three shows that an increase in time spent on grandchild care is link to a decrease in work hours over time among both grandmothers and grandfathers. Although the direction of providing each additional hour of grandchild care on employment status appears similar to the effect on work hours, it is not significant. No gender differences are found in the effect of grandchild care hours on both work hours and employment status.

Chapter four demonstrates that employed grandfathers who provide a low level of grandchild care experience a decrease in family-to-work conflict and an increase in work-to-family conflict over time compared to employed grandfathers who do not engage in grandchild care. No significant associations are found among employed grandmothers. However, employed grandfathers who engage in a low level of grandchild care are more likely to experience an increase in work-to-family conflict compared to employed grandmothers who do the same level of care. No significant evidence for gender differences in the association between grandchild care time and family-to-work conflict is found.

Results in chapter three and four collectively provide insight into both negative and positive aspects of grandchild care. Results in Chapter three indicate that an increase in time spent on grandchild care is linked to reduce grandparents’ work hours regardless of gender and may potentially produce economic repercussions, especially among grandparents who are socioeconomically disadvantaged. Results in Chapter four demonstrate the buffering effect of minimal grandchild care on family-to-work conflict and its adverse effect on work-to-family conflict among employed grandfathers. In conclusion, my dissertation sheds light on both different aspects of grandchild caregiving, with outcomes potentially depending on the level of caregiving engagement and gender.
