Public or private policies to help working parents balance job and family responsibilities are substantially more limited in the United States than in other industrialized nations. This is true for parents in general, but is particularly true for low-income working parents who hold lower wage jobs. This paper summarizes what we know about families' access to supports, employers' experiences, and public and employer efforts to expand them. It explores paid sick leave/paid time off, paid parental leave at the birth of a child, workplace flexibility, child care assistance, and initiatives to link low-income working families with public benefits.
