Working after hours has long been ingrained in American culture as a way to show how much you care about your job, to get ahead, or to appease an intense boss. Being a workaholic is often painted as a virtuous work ethic praised by leaders, a likely vestige of our Puritan roots.
Consider Elon Musk, who claimed to have once slept overnight at the Tesla factory. He’s since gone on record for encouraging similar behavior at Twitter, ordering employees to work "long hours at high intensity." And after getting some flack for the company's intense 100-hour workweeks, Goldman Sachs CEO David Solomon allowed bankers to take Saturdays off but noted that going the “extra mile” can make a big difference.
