This is a smart idea, but it made me think: I'd like to see some productivity/exercise/lifehacks for those of us who are stuck with inflexible managers or retrograde office cultures. I know I'd be vastly more productive if I could knock off around 2:00pm for a thirty-minute nap (or jog, depending) every day but unfortunately my company takes an Office Space-style approach to personnel management. It'd be great to see what people who have worked years in similar environments have been able to come up with.
