Up against one of the most powerful companies on the planet, a group of Amazon workers embark on an unprecedented campaign to unionize their warehouse in Staten Island, New York. Through intimate cinema vérité, UNION chronicles the extraordinary efforts of an unlikely group of warehouse workers as they launch a grassroots union campaign at an Amazon fulfillment center in Staten Island, New York. Led by the charismatic but underestimated Chris Smalls, the diverse band of workers start the Amazon Labor Union (ALU) and embark on a journey against one of the largest and most powerful companies in the world. The odds are stacked against them, as the group finds itself up against a tech industry giant with unlimited resources, without major support from national unions or politicians, and while navigating internal divisions within their own ranks. Filmmakers Brett Story and Stephen Maing document the struggle from day one, offering a gripping human drama about the fight for power and dignity in today's globalized economic landscape.
