Five years ago, when unemployment wasn't at all time lows like they are today, I heard stories about Amazon warehouses that simply could not hire anymore.

CHA1 in Chattanooga needs thousands of employees to function. But Chattanooga is around 180,000 people total, likely less than 100,000 working age people.

Friends of mine based there told me that the site had already hired and turned over every willing potential employee in the region. They were calling people up saying "I know we fired you two years ago because you weren't fast enough but maybe you should come back for an interview".

Sites that couldn't meet goals had their leadership fired too. Hit your rates or you're out, at all levels.

I can't imagine how bad things are now.
