WASHINGTON (AP) — The Supreme Court is weighing how much employers must do to accommodate pregnant workers under a federal law aimed at combating discrimination against pregnant women.

Questions from several justices during arguments Wednesday suggest the court could be searching for a middle ground between United Parcel Service and former driver Peggy Young.

UPS refused to give Young temporary light-duty work so that she could avoid lifting heavy packages after she became pregnant in 2006.

Young was in the courtroom Wednesday to hear the justices talk about employers' responsibilities under the 36-year-old Pregnancy Discrimination Act.
