Of all the companies in the world, the one I would be most worried about automating away human jobs would be Amazon. If this warehouse unionizes, I suspect it will quickly become their number one automation test site. As the cost of labor goes up and the cost of automation goes down, they'll have a higher incentive to do this quickly.
Just look at what they announced during re:invent this year. The AWS Panorama was basically designed to replace people in Amazon warehouses. The Amazon Go store was basically a test bed to ~~get rid of the already~~ prevent unionized labor at Whole Foods.
I wish the workers luck, but in the long term, they're probably just hastening their replacement by increasing their own costs to the company.
