Amazon is experimenting with humanoid robots for warehouse work.
The idea that Amazon will not replace every job they can regardless of unionization status is preposterous.
If they can automate the job, they already have every incentive to do so. This is not going to crack the whip.
Workers should unionize, period. The company is coming for them either way.
preposterous
You have two numbers – the expected value of the automated system, and the expected value of the human workforce. There is going to be someome estimating what the return is from each. If the automated one is a better return, that is the one that they will go with.
If they estimate strikes on the part of the human workforce, that will tend to make the human workforce less-favorable than it otherwise would be relative to the automated system.
