The UX designer probably work in a cushy Amazon corporate office with free snacks and drinks, but amazon warehouse roles are probably under more spartan and strict conditions. How does Amazon warehouse work conditions compare to other warehouse work conditions. That's the better comparable.
If any programmer was thrown into a construction or blue collar work environment they probably won't like the work conditions. But for cost reasons they can't extend the same benefits for people who sort packages the same as people who write code or design screens.
The best way to protest an employer is to not work for them. As UX designers who made it into Amazon they probably have other choices.
No, the best way to protest an employer is to speak out. "Not working" for a company like Amazon where there is an endless supply of people desperate for work does absolutely nothing. Remaining silent is what keeps the status quo going.
The rest of your comment reads like something a paid shill for Amazon would write.
And then this is besides the point, but Amazon doesn't give out free food and drink like Google does.
That's not why. Salaries are largely driven by supply and demand. If there are enough people willing to be employed at a low pay level there's no incentive to increase it.
Sorry but this is totally ineffectual compared to speaking out and organizing people on the job. Also quitting in protest doesn’t exactly make it easy to get the next job.
You might not believe it but Amazon does not offer free snacks or drinks (at least not in HQ)...
