The Inefficiency of Long Hours
Writing for The New Yorker, James Surowiecki explores the downside of working long hours:
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 [David] Solomon put it, past a certain point overworked people become “less efficient and less effective.” And the effects are cumulative. The bankers [Alexandra] 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.
