New York City Mayor Bill de Blasio said Tuesday that he has ordered the city's human rights commissioner to investigate Amazon's decision to fire a warehouse worker who organized a strike at its Staten Island warehouse.

Chris Smalls, a warehouse worker at the facility, known as JFK8, organized a strike on Monday to call attention to the lack of protective measures for workers who continue to be on the job amid the coronavirus outbreak.

Smalls claims he was fired by Amazon in retaliation for his decision to organize the strike. Amazon said it dismissed Smalls after he "received multiple warnings for violating social distancing guidelines."

"I've ordered the city's commission on human rights to investigate Amazon immediately to determine if that's true," de Blasio said at a news conference Tuesday. "If so, that would be a violation of our city's human rights law and we would act on it immediately."

De Blasio added that the New York City Sheriff's Office has inspected JFK8 to make sure it's following social distancing precautions and said that it will "continue to inspect as needed."
