According to the lawsuit, Anthony's co-workers placed a noose above his desk in March in “an act of extreme racial violence designed to intentionally inflict emotional distress.” After an investigation, Boeing fired the person responsible for the noose, which Anthony’s attorney said he learned about from reading reports in the news.

Anthony said that in recent months, after he complained about the alleged harassment, he faced retaliation by being moved to a building with no air conditioning.

A spokesman for the company told NBC News on Monday that while Anthony is "a valued Boeing South Carolina teammate," there is no validity to his claims.
