There's a reason why we call your day job a "9 to 5." That's eight hours a day we're supposed to be working, which equates
to 40 hours a week. If you're justifying
the hours with the fact that you're getting more work done, you may be wrong.
In the early 1900s, Ford Motor ran dozens of tests to discover the optimum
work hours for worker productivity
. They discovered that the "sweet spot" is 40 hours a week — and that, while adding another 20 hours provides a minor increase in productivity, that increase only lasts for three to four weeks, and then turns negative
Anyone who's spent time in a corporate
environment knows that what was true of factory workers a hundred years ago is true of office workers today. People who put in a solid
40 hours a week get more done than those who regularly
work 60 or more hours.
Adding to that, people who work long workweeks have a higher chance of burning out
. What about you — do you work more than 40 hours a week?
