The Equal Employment Opportunity Commission (EEOC) filed a lawsuit against Walmart Inc. on Friday, claiming that the Walmart did not accommodate pregnancy-related medical restrictions, and denied pregnant workers' requests for unpaid leave. The Pregnancy Discrimination Act of 1978 prohibits workplace discrimination against pregnant women; in 2015 the Supreme Court also ruled that the act addressed the need to provide the same type of accommodations to pregnant employees as it does similarly disabled workers. The lawsuit was brought on behalf of employees at distribution centers in Wisconsin; the retailer is also facing class action lawsuits in Illinois and New York for denying accommodations to pregnant women in its stores.
