There was a commenter on the sub (he might be here as well; not sure) who went beyond that and would sabotage the company in such a way as it ended up financially benefiting him. His core insight was an average office job has enough downtime where you aren't expected to do anything that it's possible to work two jobs simultaneously if one employer lets you work remotely, and that working two such lower salary jobs is easier than working one job that pays twice the salary.

I will add to this concept and say that for most large companies it's so hard to hire and fire people that managers will tend to bend over backwards to try to get any amount of productivity out of you just so they don't have to go through that nightmare again. So even if you are utterly incompetent you can probably collect multiple paychecks simultaneously for months if not years. My boss recently called to tell me he fired someone who had been working at the company for six years because he literally had no idea what this person did or was supposed to be doing. Another manager friend constantly complains to me about an incompetent employee that he was trying to fire but for some reason can't.

That's the holy grail I think: be incompetent in such a way as you end up siphoning even more money away from the company/system than you otherwise would.
