This is a great tactic, where competent, good workers find a more stable job, and the ones unable to get a better job are then rehired. On one hand, you can bully them more, and they'll stay, on the other hand, they're so bad at their job, no one else wants them either.
I believe they call this "contracting". Which is not what they purported to do. Having to go through all the bullshit about the hiring process, benefits, taxes, and all that over and over is an absurd inefficiency. It also doesn't help when people are just trying to feed and care for their families.
Because of that experience (and lots of other anecdotal evidence), I see no reason for anybody to ever work at amazon unless they are ok with being a contractor.
