Surely they're just gonna be left with visa slavery?
There's already an ick associated with working for Amazon, when they start cutting the upsides* why would anyone stick around? I'd personally take a pay cut to go elsewhere if my current job forced me to go in 5 days a week
*Though IMO hybrid working is no longer remotely considered a perk and is the expected norm in this industry now. Even before the pandemic, my previous employer already let us work from home once a week if you wanted to.
