ATLANTA, GA-UPS announced a policy change to provide more accommodations to pregnant workers in the U.S., allowing them to stay on the job through their pregnancies.

The company has said they will provide light duty work and other accommodations for pregnant employees as they do for employees with physical restrictions resulting from on-the-job injuries. The new policy goes into effect January 1, 2015.

The change comes after a former UPS employee sued the parcel and delivery giant over pregnancy discrimination.

The employee’s job with UPS required her to lift boxes as heavy as 70 lbs., but after she became pregnant, she was advised by her midwife not to lift more than 20 lbs. The woman asked UPS to put her on light duty, an accommodation the employer made for those with on-the-job injuries or disabilities, but UPS refused. The woman took an unpaid leave, but was not fired.

The employee brought the case to the district court level and the Fourth Circuit Court of Appeals and lost, until finally, she brought it to the Supreme Court.

The Supreme Court has not found UPS guilty of intentional discrimination against the employee, but the company has voluntarily changed their policy to better accommodate pregnant employees.
