Of course they are. The person in the Amazon van most of the time is a subcontractor of Amazon DSP, which sub contracts to Amazon LLC. The cleaning people are a separate company too. It’s contractors all the way down, people!
It’s intentional. You don’t have to mingle with the undesirables who clean dirty toilets at the Christmas luncheon if they don’t work for you, and they won’t bring down your numbers either.
All of Amazon is just shuffling numbers from here to there to make the robots happy so you can keep your job for just a little while longer as the churn and burn through the human population with selectively enforced unrealistic work demands like packing 280 individual items per hour with less than a certain percentage of kick outs. Then when you aren’t good at a specific task they write you up and lock you into it until they can terminate you for performance issues.
Here’s my sarcastic comment: Shocking!
