I don't think that's what that stat says.
For instance, if Amazon hired ten people in January, retained 5, fired 5 in February, and replaced them. Then, I fired 3 in March and replaced them. Then fired 2 in April, and replaced them. Then, fired 1 in May and replaced them. That's consistent with having candidates that only meet job requirements 50% of the time. But it would show up as 100% turnover.
That's not the same thing as people not wanting to work there. Warehouse jobs are demanding, but pay relatively better for unskilled labor than other jobs. And the workforce that is available for those jobs is often not the best in terms of skills and work habits.
These are things you learn when you run a small business. The American domestic high school educated workforce in most cities is very unreliable. You have more luck with immigrants, but if for some reason you can't hire illegals (like Amazon) then you are kinda at the mercy of having a workforce that often doesn't show up for shifts, has difficulty reading and following instructions, etc.
I encourage everyone that wants to fight for more worker rights to start a business that uses unskilled labor and provide those workers with some more rights.
Hiring American top-25 college grads to work in a startup isn't the same thing.
