According to a new study, offering employees pizza as a reward for increased productivity does more to motivate them than cash. Apparently, melted cheese on tomato-y bread beats having more money after rent and food-that-is-not-pizza. It sounds weird, but think of it this way: employees already get paid some money and zero pizza. More money is nice, but that's an infinity percent increase in pizza! (More importantly, the whole team enjoys pizza together and people value social approval a lot.)
