WASHINGTON — The Supreme Court will take up the pregnancy discrimination claims of a package delivery driver for UPS who was refused a light duty assignment so she could continue working while pregnant.

UPS driver Peggy Young lost her health benefits when UPS would not grant her light duty or allow her to continue her regular job. Young says the company allows employees with some medical conditions to perform jobs in which they can avoid lifting heavy packages. She returned to work after giving birth.

Lower courts ruled that UPS did not violate the Pregnancy Discrimination Act in dealing with Young.

The case will be argued in the fall or winter.

The Obama administration agreed with Young, but said recent changes in federal law could cause courts to rule in another way.
