He was not crushed by machinery or anything:
"Dariusz worked so hard. His job used to be done by a few people during a shift, but then they made him do all that work alone, pushing around trolleys with heavy boxes."
He was simply pushed working too hard. So a robot doing the job would have been one solution - the other simply an extra human helping, or switching tasks, to something less physically demanding.
However the difference, is that in the utopia inside my head, we start taxing the rich/corporations and provide UBI to people, our goal should be to mechanise/automate everyone out of jobs where possible and allow them to do whatever they want to with their lives.
The sad truth of the world is smart people invented a machine that can make 10,000 widgets per hour instead of 1 per hour by hand, but did that mean the price of widgets went down? No, and all of the benefits of this machine were reaped solely by a bunch of parasites in suits and ties, who contribute nothing to the world.
Amazon is not punished. That woman was only reinstated in her rock-bottom-wage, back-breaking/RSI-inducing Amazon job.
If she'd have gotten some large sum of money as compensation, or if the court had ordered Amazon to enter good-faith negotiations with the union, or accept some of its demands, or to cease warehouse operations temporary etc. - that would have been punishment.
