Why We Have to Go Back to a 40-Hour Work Week to Keep Our Sanity
Continued from previous page
The other thing about knowledge workers is that they’re exquisitely sensitive to even minor sleep loss. Research by the US military has shown that losing just one hour of sleep per night for a week will cause a level of cognitive degradation equivalent to a .10 blood alcohol level. Worse: most people who’ve fallen into this state typically have no idea of just how impaired they are. It’s only when you look at the dramatically lower quality of their output that it shows up. Robinson writes: “If they came to work that drunk, we'd fire them -- we'd rightly see them as a manifest risk to our enterprise, our data, our capital equipment, us, and themselves. But we don't think twice about making an equivalent level of sleep deprivation a condition of continued employment.”
And the potential for catastrophic failure can be every bit as high for knowledge workers as it is for laborers. Robinson cites the follow-up investigations on the Exxon Valdez disaster and the Challenger explosion. Both sets of investigators found that severely overworked, overtired decision-makers played significant roles in bringing about these disasters. There’s also a huge body of research on life-threatening errors made by exhausted medical residents, as well as research by the US military on the catastrophic effects of fatigue on the target discrimination abilities of artillery operators. (As Robinson dryly notes: “It's a good thing knowledge workers rarely have to worry about friendly fire.")
“Passion," De-Unionization, and the End of the 40-Hour Week
How did this knowledge, which was so deeply embedded in three generations of American business management that it was utterly taken for granted, come to be so lost to us now? There are probably several answers to that, but there are three factors in particular that stand out.
The first is the emergence of Silicon Valley as an economic powerhouse in the late 1970s. Since WWII, the valley had attracted a unique breed of worker — scientists and technologists who carried with them a singular passion for research and innovation. Asperger's Syndrome wasn’t named and identified until 1994, but by the 1950s, the defense industries in California's Santa Clara Valley were already drawing in brilliant young men and women who fit the profile: single-minded, socially awkward, emotionally detached, and blessed (or cursed) with a singular, unique, laser-like focus on some particular area of obsessive interest. For these people, work wasn’t just work; it was their life’s passion, and they devoted every waking hour to it, usually to the exclusion of non-work relationships, exercise, sleep, food, and sometimes even personal care. The popular stereotype of the geek was born in some real truths about the specific kinds of people who were drawn to tech in those early years.
The culture that grew up in the valley over the next few decades reflected and valorized the peculiarities of what Lockheed’s company psychologists were calling by the late '50s “the sci-tech personality.” Companies broadened their working hours, so programmers who came in at noon and worked through till midnight could make their own schedules. Dress codes were loosened; personal eccentricities were celebrated. HP famously brought in breakfast every morning so its engineers would remember to eat. The local 24-hour supermarket carried microchips alongside the potato chips, so techies working in their garages could stop in at 2am for snacks and parts.
And then, in the early ‘80s, Tom Peters came along, and promoted the Silicon Valley work ethic to the rest of the country in the name of “excellence.” He extolled tech giants like HP and Apple for the “passion” of their workers, and told old-industry employers that they could move into the new age by seeking out and rewarding that kind of passion in their employees, too. Though Peters didn't advocate this explicitly, it was implicitly understood that to "passionate" people, 40-hour weeks were old-fashioned and boring. In the new workplace, people would find their ultimate meaning and happiness in the sheer unrivaled joy of work. They wouldn't want to be anywhere else.
