Background: Paid maternity leave benefits all of society, reducing infant mortality and providing economic gains. It is endorsed by international treaties. Paid maternity leave is important for breastfeeding, bonding, and recovery from childbirth. Not all mothers have access to adequate paid maternity leave. Key Information: Paid leave helps meet several of the 17 United Nations' Sustainable Development Goals (2, 3, 4, 5, 8, and 10), including fostering economic growth. A family's expenses will rise with the arrival of an infant. Paid leave is often granted with partial pay. Many low-wage workers earn barely enough to meet their needs and are unable to take advantage of paid leave. Undocumented immigrants and self-employed persons, including those engaging in informal work, are often omitted from maternity leave programs. Recommendations: Six months of paid leave at 100% pay, or cash equivalent, should be available to mothers regardless of income, employment, or immigration status. At the very minimum, 18 weeks of fully paid leave should be granted. Partial pay for low-wage workers is insufficient. Leave and work arrangements should be flexible whenever possible. Longer flexible leave for parents of sick and preterm infants is essential. Providing adequate paid leave for partners has multiple benefits. Increasing minimum wages can help more families utilize paid leave. Cash benefits per birth can help informal workers and undocumented mothers afford to take leave. Equitable paid maternity leave must be primarily provided by governments and cannot be accomplished by employers alone.
