Peggy Young delivered letters and packages sent by air for UPS. When she got pregnant after struggling with infertility and IVF, her doctor recommended that she not lift more than 20 pounds. She asked UPS, where she had worked since 1999, for a "light duty" assignment, so that she could continue working through her pregnancy.
UPS said no. It explained that its policy was to offer light duty assignments or "inside" jobs to lots of different kinds of workers who were temporarily unable to perform their regular tasks: workers who were injured on the job, workers with a qualifying disability under the Americans with Disabilities Act, workers who lose their commercial driving licenses because of an off-the-job injury, and workers involved in a car accident.
As a result, Peggy was put on unpaid leave with no medical coverage.
Sound illegal? It is, and has been since 1978, when Congress amended the civil rights laws to require employers to treat pregnant workers the same as any other worker who is similar in his or her ability or inability to do the job. The Pregnancy Discrimination Act of 1978 is supposed to guarantee that, if the boss offers any other class of temporarily disabled workers a benefit or accommodation – like light duty, extra bathroom breaks, access to water, or a modified schedule – pregnant workers are given the same treatment.

In Hulteen, Noreen Hulteen and three other women sued AT&T for reducing their pension benefits because they took time off work for pregnancy and childbirth. Two of the women were actually required by AT&T to take time off - a reflection of workplace practices at the time that presumed that all pregnant women were unfit to work or unwelcome because of their "condition." AT&T provides pension benefits based on a seniority system calculated based on years of employment minus uncredited personal leave time. Until the late 1970s, AT&T treated pregnancy and childbirth leave as uncredited personal time even though all other medical leave resulted in full service credit for the entire period of absence. Decades later, Ms. Hulteen and the other women learned that they were receiving a smaller pension benefit because of the uncredited pregnancy leave. The women argued that this calculation violated Title VII as amended by the
