This paper was prepared by the Institute for Women’s Policy Research (IWPR) as a part of a series of Scholars’ Papers sponsored by the U.S. Department of Labor Women's Bureau in commemoration of the 50th Anniversary of American Women: Report of the President’s Commission on the Status of Women, 1963.

This briefing paper summarizes employees’ legal rights in relation to pregnancy, childbirth and adoption, and nursing breaks, and examines how far employers are voluntarily moving to provide paid parental leave beyond basic legal rights. It draws on three data sources: leave benefits offered by Working Mother magazine’s “100 Best Companies,” the Family and Medical Leave Act in 2012 Survey, and the National Compensation Survey.

The United States is among a very small number of countries in the world without a statutory right to paid maternity leave for employees. The Institute for Women’s Policy Research’s (IWPR) analysis of Working Mother magazine’s “100 Best Companies” finds that almost all of the top companies provide some paid maternity leave and, between 2006 and 2010, these employers dramatically expanded coverage for paternity and adoptive parent leave.

In developing a simulation model to estimate the cost of paid family and medical leave programs in a given state, we rely on data documenting known leave-taking behavior. Where this is not possible, we provide a set of reasonable assumptions about unknown aspects of behavior in the presence of a paid leave program.

Nearly one-quarter (24 percent) of the best employers for working mothers provide four or fewer weeks of paid maternity leave, and half (52 percent) provide six weeks or less, according to an Institute for Women’s Policy Research analysis of data provided by Working Mother Media, Inc., publisher of Working Mother magazine.
