The newspaper interviewed 20 people who worked in an Amazon warehouse in the Lehigh Valley in Pennsylvania. They described, and the newspaper verified, temperatures of more than 100 degrees Fahrenheit, or 37 degrees Celsius, in the warehouse, causing several employees to faint and fall ill and the company to maintain ambulances outside. Employees were hounded to “make rate,” meaning to pick or pack 120, 125, 150 pieces an hour, the rates rising with tenure. Tenure, though, wasn’t long, because the work force was largely temps from an agency. Permanent jobs were a mirage that seldom came. And so workers toiled even when injured to avoid being fired. A woman who left to have breast cancer surgery returned a week later to find that her job had been “terminated.”
