I was thinking about this the other day and while I’m sure they would never admit it, I think the reason Amazon is so anti-union is to prepare for automation.
Whenever they can reliably replace all the low-income employees with robots, they will do so. If employees had a union they might be able to stop or slow the replacement of people with robots.
