Plaintiff brought a claim of pregnancy discrimination alleging that her employer violated the Pregnancy Discrimination Act by refusing to accommodate her pregnancy related lifting restriction. The Supreme Court held that a petitioner may state a prima facie case of pregnancy discrimination according to the McDonnell Douglas Corp. v. Green burden-shifting framework by showing: (1) she belongs to a protected class; (2) she sought an accommodation; (3) the employer refused to accommodate her; and (4) the employer has accommodated others "similar in their ability or inability to work." If a petitioner makes out a prima facie case of discrimination, the employer may rebut with legitimate, nondiscriminatory reasons for refusing to accommodate the employee. The employee must then establish that the employer's justification is pre-textual. The Supreme Court determined that there was a question as to whether the UPS provided more favorable treatment to other employees under similar circumstances and remanded the case for judgment.
