Drawing from U.S. state legislative documents, this chapter examines the development of subnational leave policies across states and over time. The research identifies 72 leave laws adopted by states between 1942 and 2017 and shows how some states are more active than others. In comparison to other countries, states quickly abandoned female-targeted policies in favor of gender-neutral, individual entitlements, and leave rights in the United States can be uniquely distinguished by whether they provide time-off to address medical or caregiving needs. I argue that American lawmakers have an opportunity to layer wage-replacement benefits on top of preexisting, gender-neutral and individual entitlements to job-protected leave in a step toward gender-egalitarian family policy models found in other countries.
