The ability of employed parents to meet the health needs of their children may depend on their access to sick leave, especially for low-income workers. By examining access to paid sick leave and paid vacation using the 2003-2004 Medical Expenditure Panel Survey, the authors find that low-income families are less likely to have access to paid leave, especially if the family lacks a full-time/full-year worker. Among children whose parents have access to paid sick leave, parents are more likely to take time away from work to care for themselves or others.
