I know you posted this as a joke, but the CIA’s Simple Sabotage handbook recommends doing something exactly like this. If you can’t risk your cover with active sabotage, you can still contribute by getting a position in middle management and doing everything in your power to grind the gears of bureaucracy to a halt.

Let’s say there’s a company that is manufacturing war supplies. You can apply for middle management positions, and then do the typical “middle management is so inept” thing to slow down production.
