The Supreme Court is taking up a pregnancy discrimination case with the potential to affect many American women who continue to work throughout their pregnancies.
The case before the justices Wednesday involves a former driver for United Parcel Service who wanted a temporary assignment to avoid lifting heavy packages after she became pregnant in 2006.
UPS refused to accommodate driver Peggy Young, who was on unpaid leave until two months after she gave birth.
The court is weighing whether the company's actions violated the Pregnancy Discrimination Act.
Young says she should have been offered light-duty work because some UPS workers were.
The Atlanta-based package delivery company says it will voluntarily offer pregnant women light duty starting in January. But the company contends it complied with the law in Young's case.
