Pros
Flex hour blocks are ok
Cons
Every single process at Amazon is designed to squeeze the heck out of its workers - whether it is the warehouse workers, corporate workers, or delivery drivers. As expected, Amazon creates delivery package distribution based on some buggy and invalidated algorithms and the drivers pay the price for that inaccuracy. If a driver has to make 50 deliveries in 3 hour blocks, what is based on? A simulation, actual data, test results? As an engineer who does this for some side money, I can vouch this with my years of college experience and designing simulations that Amazon Flex comes up with delivery packages with models that maybe 50% accurate at best. That is why you will always be able to deliver the allotted packages in 3 hour blocks only half the time. So when is Amazon Flex wrong half the time, who takes the brunt, it is the drivers who essentially work for the richest greedy CEO in the world for free.
