It was about 3am on a night shift in May last year when Amazon worker Christine Manno tried to retrieve a box stacked high in the warehouse in St Peters, Missouri. She was 30ft in the air, strapped to a harness and standing on the edge of the raised platform of a truck.
She was recovering from operations on her injured hands for carpal tunnel syndrome, a neurological disorder, and the weight of the box shot pains through her neck and back. “It was like an electric shock,” she said.
