Johnson Controls, Inc. ("Johnson") manufactures batteries whose assembly process entails exposure to high levels of lead. After discovering that eight of its female employees became pregnant while maintaining blood lead levels in excess of those thought safe by the Occupational Safety and Health Administration (OSHA), Johnson barred all its female employees - except those with medically documented infertility - from engaging in tasks that require exposure to lead in access of recommended OSHA levels. Following its passage, the United Automobile Workers (UAW) challenged Johnson's fetal-protection policy as sexually discriminatory in violation of Title VII of the 1964 Civil Rights Act (Act). When the Appellate Court affirmed a district court decision in favor of Johnson, the UAW appealed and the Supreme Court granted certiorari.
