Having nothing to do at work is its own form of torture.
If you have to be available and connected, or much worse - physically in the office, for the full normal work day, it is torture. Once you've gone through the ceremony of getting ready for work, commuting, and being the building.. you might as well have something to do.
Another a second form of torture in this category is being treated like your app/role is being dead-ended, but also everything you are working on is super urgent permanent fire drill mode. Usually this is some flavor of an app being deemed "legacy" and most of the staff being moved to "the new thing" which is perpetually 5 years behind schedule. Someone once remarked that "legacy" is often better known as "production". So while you are told all about how your team/app is going away, there's nowhere for the users to go, so you are fielding the brunt of overnight pages, mid-day fire drills, etc.
Lastly, I can relate to "Recovery will take time but at least I know I wont get verbally berated every time something isn't perfect." I had two bosses like this in my career, and the behavior it encourages is for everyone to keep their head down and have sloppy shoulders. Don't be proactive, only do the immediate task requested of you because it minimizes the amount of things that could get you screamed at.
These guys are harder to screen for than you'd imagine, as both of them could turn it on & off, and appear as the nicest guys in the room, especially at the pub.
For me, all three are a form of feeling helpless and having lost agency.. which is what drives the most anxiety for me. Changing jobs every 4-5 years allows one to minimize their time in these situations as they occur.
