Working Too Much Is Bad For Business

So why do we do it?

The perplexing thing about the cult of overwork is that, as we’ve known for a while, long hours diminish both productivity and quality. Among industrial workers, overtime raises the rate of mistakes and safety mishaps; likewise, for knowledge workers fatigue and sleep-deprivation make it hard to perform at a high cognitive level. As Solomon put it, past a certain point overworked people become “less efficient and less effective.” And the effects are cumulative. The bankers Michel studied started to break down in their fourth year on the job. They suffered from depression, anxiety, and immune-system problems, and performance reviews showed that their creativity and judgment declined.

If the benefits of working fewer hours are this clear, why has it been so hard for businesses to embrace the idea? Simple economics certainly plays a role: in some cases, such as law firms that bill by the hour, the system can reward you for working longer, not smarter. And even if a person pulling all-nighters is less productive than a well-rested substitute would be, it’s still cheaper to pay one person to work a hundred hours a week than two people to work fifty hours apiece.
