Volumes have been written about the dangers of overwork, but a recent article captured just how bad it is for us…and how we get less done. Here’s how it begins:
Jack Ma, the richest man in China and founder of the e-commerce company Alibaba, is a big fan of extreme overwork. He recently praised China’s “996” practice, so called because it refers to those who put in 12-hour days — 9 a.m. to 9 p.m. — six days a week. This “is not a problem,” he said in a recent blog post, instead calling it a “blessing.”
The response from others in China was swift. “If all enterprises enforce a 996 schedule, no one will have children,” one person argued on the same platform. “Did you ever think about the elderly at home who need care, the children who need company?” It even prompted a response from Chinese state media, which reminded everyone, “The mandatory enforcement of 996 overtime culture not only reflects the arrogance of business managers, but also is unfair and impractical.”
Managers who think like Mr. Ma can be found the world over. Here at home, Elon Musk, a co-founder of Tesla, has argued that “nobody ever changed the world on 40 hours a week.” Uber reportedly used to use the internal mantra “Work smarter, harder and longer.” (It’s now just “smarter” and “harder.”) The company has also rebranded second jobs as clever “side hustles.” WeWork decorates its co-working spaces with phrases like, “Don’t stop when you’re tired, stop when you are done.” Other tech and business gurus try to sell us on “toil glamour.”
The truth is that they’re all wrong. Workers certainly suffer when forced to put in extreme hours. But business fares just as poorly. No one benefits from people pushing themselves to the brink of exhaustion.
The Centers for Disease Control and Prevention has also warned that putting in extra hours is associated with poorer health, including weight gain and higher alcohol and tobacco use, and increased injury, illness and even mortality. Health researchers have found that overwork is linked to a higher risk of heart disease and stroke.
There’s a ceiling on how much more someone can get done by simply spending more time at work. After about 48 hours a week, a worker’s output drops sharply, according to a Stanford economist. Other research has appeared to support this finding. While there may be an initial burst of activity from overworking, people who work more than 55 hours a week perform worse than those who go home at a normal hour and get some rest.
