I worked for AWS, it was one of the best jobs I’ve had and the only one in decades where I could leave the office, not think about work at all until I came back in, and not feel the slightest bit guilty or anxious about that. I know others have had a very different AWS experience.
Also anecdotally, I’d always chat to the facilities team/janitors at if they were in the kitchen while I was having lunch. All of them also worked shifts at the distribution center that opened up nearby. Their only complaint was they couldn’t get enough shifts there. It paid better than cleaning the kitchens in the corporate offices. Again, no doubt there’s a wide range of experiences.
