Until now, Amazon’s U.S. workers haven’t walked off the job during key sales days. About 250 union pilots who haul packages for Amazon and DHL Worldwide Express staged a brief strike in the leadup to Thanksgiving in 2016 before a federal judge ordered them back to work, eliminating any disruptions during the peak holiday shopping season.
