What rock are you living under? Plenty of the documented absolute nightmare of working for Amazon in their warehouses is corroborated by their own internal analysis. Unions are for more than just making sure people don't die when doing their job. The union I am a member of more than doubled the wages of its members after its first 12 years of existence. Crucially it also ensures twice yearly cost of living adjustments. It is the only way for labor to have a meaningful negotiating position. There are shitty unions out there, but there are a lot of shitty employers too. Amazon's internal reporting shows they're going to exhaust the labor pool in several areas because they've cycled through everyone who could possibly work at the warehouses and fulfillment centers. People aren't leaving Amazon because they aren't allowed to use the bathroom. They're leaving Amazon because it is dehumanizing and miserable. Funny how the people who make the lowest wages have to put up with the most shit.
