A lengthy Bloomberg report says that Amazon Flex drivers are supervised, and often fired by algorithms and e-mails rather than human beings. If you're not familiar with it, Amazon Flex is basically Postmates but for delivering Amazon packages--basically, you can sign up to deliver packages with your own vehicle. Flex started in 2015 as a way for Amazon to get its packages out the same day to local customers (and of course, use gig workers instead of hiring--ED), growing to now include same-day grocery delivery. Algorithms monitor Flex drivers and how they do their jobs, grading them on a rating system that drivers obsess over--and for good reason. But the moment they sign on, Flex drivers discover algorithms are monitoring their every move. Did they get to the delivery station when they said they would?
