I actually agree with you over the other comments. I think the idea of industriously trying to be the worst worker you possibly can (while not being fired) is one of those self-defeating efforts to do less work where you actually do more work in a lot of ways. You've got to justify to yourself continually that you're not being a drain or a bad person. You've got to juggle context switching between two roles during an overlapping period, making both more difficult than they would be individually and leaving yourself worse able to focus generally. (I suppose you could probably block your schedule to make this work better but I can't see a silver bullet solution for all the time.) You've got to compartmentalize your jobs and your interaction with coworkers. I know that with my personality, these factors would be major drags on my mental and emotional well-being. I would feel like a fraud for a long time before getting used to something like this.

With a business, while you deal with some similar issues (compartmentalization, context-switching), I expect they'd feel far less invalidating (again, to me/those with similar personality types) because you'd know you were actually applying yourself to do the best you could.
