Rina Cummings has worked three 12-hour shifts every week at Amazon’s gargantuan New York City warehouse, called JFK8, on Staten Island since it first began operations in late 2018. As a sorter on the outbound ship dock, her job is to inspect and scan a mandated rate of 1,800 Amazon packages an hour – 30 per minute – that are sent through a chute and transported on a conveyor belt before leaving the facility for delivery.
