I've come to realize that if Amazon does something, it gets a ton of coverage.
4x10 shifts are not a new concept. This article makes it sound like what is pretty standard warehouse stuff is a new diabolical amazon plan to create the soul crushing "megacycle".
And working nights is not new. Anyone who has had to deal with 24x7 staffing (police, guard, nursing, flying etc etc) has had come up with approaches for night shift work (which is definitely terrible). Heads up, the non-megacycle night shift is also no fun for a lot of people.
That said, night shift work is miserable. No question there!
