I wrote a long article for SiliconAngle on research into overtime and the 40 hour work week. It turns out that in most cases overtime and lack of sleep do more harm than good:
Facebook COO Sharyl Sandberg has kicked up a mini-controversy by admitting to Makers.com that she leaves the office at 5:30PM every day, and has done so for years. In the Valley, where work is a religion, leaving early is heresy.
Earlier this week “Jon” published The 501 Developer Manifesto, a call for developers to spend less time working.These calls for less time at the office are counter balanced by a recent talk by Google executive Marissa Mayer at an 92|Y event. Mayer dismissed the phenomena of “burn out” as resentment and boasted of working 130 hours a week at times.
Research suggests that Sandberg is probably the more productive executive, and those 501ers may be on to something. In a lengthy essay titled “Bring back the 40-hour work week,” Alternet editor Sara Robinson looks at the history of long working hours and reminds us why the 40 hour limit was imposed in the first place: working more than 40 hours a week has been shown to be counterproductive. It’s a relevant conversation for IT workers, who according to ComputerWorld average 71 hours of work per week.
