Former worker sues Costco over alleged sexual harassment by female boss

A former employee has filed a lawsuit against Costco in Manhattan Supreme Court, claiming she was fired after reporting sexual harassment by her female supervisor. The New York Post reported that the lawsuit was filed on October 1 by an anonymous woman from the Bronx. [1]

According to the New York Post, the plaintiff worked at the East Harlem Costco located on East 117th Street for two years. She alleges that her supervisor, Andrea Mills, created a hostile work environment through inappropriate behavior. [1]

The New York Post reported that the alleged misconduct began in October 2024 during a meeting where Mills complained about the shirt the worker was wearing. The plaintiff was wearing an official Costco crew neck uniform at the time of the incident. [1]

The plaintiff claims that after she reported the harassment created by her direct supervisor, Costco terminated her employment in January 2025. The lawsuit alleges that her firing was direct retaliation for sounding the alarm about the workplace conditions. [1]
