Most likely he worked for a Logistics company that was contracting with Amazon. My daughter works for a logistics company that contracts with Amazon. Prior to that she was an independent contractor employed by Amazon but she used her own vehicle. Not sure but I don't think there are actually any "Amazon" drivers running routes.My nephew worked for Amazon as a delivery driver. Had unreasonable delivery load and a crappy van they would not fix. He finally got fed up and lefty.
