Though there are pregnancy discrimination laws already enacted, clearly some employers simply don’t get it. On September 19, 2012 the Pregnant Workers Fairness Act (S. 3565) was introduced into the Senate. The purpose is:
To eliminate discrimination and promote women’s health and economic security by ensuring reasonable workplace accommodations for workers whose ability to perform the functions of a job are limited by pregnancy, childbirth, or a related medical condition.
It was modeled after the Americans with Disabilities Act (ADA) and would prevent employers from forcing pregnant women out of the workplace by placing them on unpaid leave, firing them, or forcing them to quit when they are denied the accommodations they need to continue working safely.
The Pregnant Workers Fairness Act would also help ensure that employers provide job modifications when it would allow a woman to continue working during pregnancy.
