I work these same companies. It’s not about bad bosses, it’s the C-Level people in your news feed degrading their entire workforce via the press. It’s hearing your job is going to be “phased out” if you don’t start reporting to an office hours away after being hired for remote work. It’s having your pay slashed and being told to “deal with it, or find a new job” via email on Monday, then hearing about it all over the news on Tuesday to really hammer it home that you have to fear for your job, and they’ll absolutely replace your ass if you say anything about it.
This was all done by Amazon, Google, and Microsoft in the past year at various different times as if it work from a guidebook on demoralizing your workforce.
