Amazon faces a nationwide class-action lawsuit alleging it systematically discriminated against pregnant employees by denying reasonable accommodations, retaliating against workers who requested them, and firing employees whose unpaid time off was depleted by medical appointments and breaks. The suit, brought by four former warehouse workers, claims the company violated the Pregnant Workers Fairness Act through excessive documentation requirements, minute-by-minute monitoring of lactation breaks, and automatic deduction of medical time from limited paid time off banks.
