Your lazy coworker could actually be helping by doing nothing

Lazy coworkers don't just exist in the office — it turns out the animal kingdom has its equivalent of the guy who takes two-hour coffee breaks.

Hasegawa's study, which was published in Nature and reported by NPR, focused on ants. According to his research, ants love to slack off: At any given time, about half of the ant colony is just wandering around, not moving, or grooming.

"Even when observed over a long period of time, between 20 and 30 percent of ants don't do anything you could call work," Hasegawa told NPR.
