Something tells me people will find a way to complain about this. And that those people will be the same people that think Amazon's warehouse policies are oppressive.
It's because the alternatives are still worse. And now they'll lose those jobs and have to face those alternatives.
Of course those of us who perceive this as an injustice will complain. The complaint is not directed at Amazon only, it's at the injustice of systemic oppression of the working class.
