On June 27, 2023, the Pregnant Workers Fairness Act (PWFA) went into effect. Under the PWFA, private and public sector employers with fifteen or more employees are required to provide a reasonable accommodation to a worker’s known limitation related to pregnancy, childbirth, and related medical conditions, unless the accommodation will cause the employer an undue hardship, which is defined as significant difficulty or expense for the employer. Read more about PWFA in the Human Resources chapter of The Gold Book.
