I’m 41, and have worked through the entire scamdemic. Some people have better work ethics than other people.
Some people do have excellent work ethics, but Amazon uses metrics where you basically have to be in the top third of the human population for physical fitness, but they don’t pay accordingly.
It’s not about your individual work ethic at Amazon.. What happens is if you’re a major producer they increase your quota/metrics accordingly and demand that you produce even more. And if you hit a plateau of maximum production then they’ll fire you for not increasing production at a steady rate.
The ironic thing is that you’re better off starting out as a slack ass who can show steady improvement over a period of time.
