There's almost zero chance they backtrack on this. Amazon is looking to reduce costs, this is fairly cheap since people will quit. Anyone who is irreplaceable will be exempted.
When I worked at Google everyone always said their favorite thing about work was their coworkers but when push came to shove they aren't willing to organize to help them. I get why many people don't want to organize but it made me happy to be gone, without cooperation they've just continued to be yanked around by management. I loved my coworkers, when management was shitty to them I wanted to fight!
Well, until layoffs are announced
Some employees are like the Boxer character from Animal Farm[1]. I vividly recall Amazon employees complaining about Amazon's new leadership principle "strive to be Earth's best employer", and once the job cuts started to hit home there were employees attacking fellow employees with jabs such as "being the Earth's best employer means those who do not like it should just leave", and "you're whining here but 10 would eagerly take your place".
One of the biggest scams is making you believe that your fellow employees are looking out for your best interests, as there were no backstabbers around.
This was very clear from the start, even the timing of mandating RTO while announcing mass layoffs. I don't know what compells anyone within Amazon to focus on the red herring.
