Morning sickness? Prenatal check-ups? What to know about new rights for pregnant workers

Pregnant employees have the right to a wide range of accommodations under new federal regulations for enforcing the Pregnant Workers Fairness Act that supporters say could change workplace culture for millions of people.

The Equal Employment Opportunity Commission, the agency in charge of enforcing the law, adopted an expansive view of conditions related to pregnancy and childbirth in its proposed regulations, including a controversial decision to include abortion, fertility treatment and birth control as medical issues requiring job protections.

The rules, which were adopted on a 3-2 vote along partisan lines, were published Monday and offer extensive guidelines for addressing more routine difficulties of pregnancy, such as morning sickness, back pain and needing to avoid heavy lifting. Labor advocates say the law will be especially transformative for pregnant women in low-wage jobs, who are often denied simple requests like more bathroom breaks.
