Henry Ford invented breaks to extract more out of the peasant Labour.
The fact we're years later and cognitively demanding jobs don't support this well show how amateur managers are and his spineless devs that enable them are.
What are you talking about? I take hour long video game breaks and nap breaks in addition to lunch. I probably actually code for like 3 hours a day, but I get more done in those 3 hours after charging up than if I'd sit there staring at code for 3 hours.
