A Bronx woman claims she was fired from Costco after sounding the alarm that her female boss was allegedly sexually harassing her.

The anonymous accuser alleges she was fired from the East Harlem Costco on East 117th in January 2025 after working there for two years because she reported the “hostile environment” created by her direct supervisor, Andrea Mills, according to the complaint filed Oct. 1 in Manhattan Supreme Court. 

Mills’ alleged inappropriate behavior began during an October 2024 meeting when she complained about the shirt the accuser was wearing – a Costco crew neck uniform.

When another supervisor allegedly asked for clarification on what the issue was, Mills shouted at the woman: “You’re a very busty woman!”  

During her next shift, Mills allegedly came up behind the woman while she was working the cash register, “invaded [her] personal space” and sang to her that she was “the most beautiful girl in the room,” per the complaint.

The accuser claimed in the filing that Mills “continued to sexually harass” her in an attempt to force her to quit her job. It’s not clear why she believed that Mills wanted her to quit.

While she never quit, she asked to leave work early after becoming uncomfortable around Mills on several occasions and took at least one approved day off, according to the lawsuit.

The woman claimed she made at least five verbal complaints to other bosses and formally reported the alleged misconduct, but no action was taken.

She even allegedly heard another supervisor brand her as a “troublemaker” for complaining. 

One of her performance reviews even allegedly read: “[She] needs to stop thinking people are attacking her.”

Her problems with Mills came to a head in December 2024 when the pair allegedly got into a heated argument over how a customer outburst was handled at the register.

Both women were sent home, but only the accuser was fired in January 2025. She claims this was an act of retaliation. 

Mills, the attorney of the accuser and Costco did not return requests for comment.
