The efforts to unionize the Staten Island site were led by union organizer and former Amazon employee Christian Smalls. He was greeted by cheers and the popping of champagne as he and other officials left the NLRB offices after the count came in.
"I'm excited that we're making history," Amazon employee Tristan Dutchin told The Associated Press. "We're about to unionize a multibillion-, trillion-dollar company. This will be a fantastic time for workers to be surrounded in a better, safer working environment."
The Biden administration also expressed support for the move with White House press secretary Jen Psaki saying that "The president was glad to see workers ensure their voices are heard with respect to important workplace decisions."
Presiden Joe Biden "believes firmly that every worker in every state must have a free and fair choice to join a union and the right to bargain collectively with their employer," she added.
David Cornfield, a labor expert and sociology professor at Vanderbilt University, told Reuters that the successful vote is a "momentous victory for working people who are doing homegrown union organizing."
He said the victory in New York would encourage others seeking to unionize workplaces across the US. "There's already a wave [of activism] occurring," he said, "and this will encourage more of that."
