"It wasn't until the middle of the twentieth century that the tipping point came along for the driverless elevator as the result of a strike by the elevator operators' union in New York City in 1945.
The strike was devastating, costing the city an estimated one hundred million dollars. Suddenly, there was an economic incentive to go back to the automatic elevator. Over the next decade there was a massive effort to build trust in automatic elevators, which resulted in the elimination of tens of thousands of elevator operator jobs."
If Amazon is close enough to automating these jobs, then it will likely just automate it and fire whoever it can. If not, then you're likely making the path towards that faster.
I don't see any way for the employees to win this beyond buying a bit more time. Unless the employees, the government, and Amazon, find a way for them to get a profession in which they have more leverage thanks to the *high individual value* they provide, rather than being a temp for future robots.
One solution can be for a union, government, Amazon etc, is to put aside money for a fund that will invest in training these employees so they could one day not depend on these kind of low-leverage jobs.
