Two-time Best Documentary Feature Oscar® winner Barbara Kopple nabbed her first in 1976 for Harlan County, USA, which chronicled Kentucky coal miners’ bitter but ultimately successful strike for better working conditions. 1990’s American Dream was less upbeat: Threatened with pay cuts or no jobs at all, Minnesota meatpacking-plant workers found a decade of Reaganomics had thoroughly weakened their bargaining power. Decades later, the director’s focus is a whole new labor sector as she completes the trilogy she began 50 years ago. Those who serve UPS, Amazon, and apps like Door Dash deliver 2.4 million packages every day within NYC alone. Many aren’t official employees but third-party contractors sans benefits or job protection, their toil frequently underpaid, exhausting, sometimes downright dangerous. Meanwhile, the corporations themselves make astronomical profits. Can unions, activism, and strikes still secure livable wages, among other basics that are rapidly disappearing for many in the 21st century? Full of real-life drama and compelling personalities, Kopple’s latest is a true sign of our times. —Dennis Harvey
