There is extremely good documentation on Amazon low-end workforce abusive practices. Not being able to take bathroom breaks as a driver or warehouse worker because the quota is set too high is a problem. Just having slightly higher than federal minimum wage does not solve those problems.
Working at amazon fulfillment centers IS a bit of a hell hole. The contractor workforces are also hellholes. Poverty in the US is a hell hole. Amazon should not be defended, they should be forced to treat workers with human dignity and respect, because clearly they nor their three layer deep cleaning contractor workforce peers will do it otherwise.
