Scientists confirm we should only work 4 days a week
Wouldn’t it be nice to have a three day weekend every week? Well, that’s what some people are calling for in the aims of productivity and worker happiness and health. There is a real cap on our productivity and after we hit it, we lose the ability to do our job at our best.
Unfortunately, people feel that by living at their desks they can get more done. By constantly buying into this cycle, we run the risk of running ourselves ragged and not performing how we should. That’s why more and more companies are adopting shorter work weeks, to make their employees happiness a priority and to create better more well-adjusted people who come to work ready to be productive.
Four or five hours per day
There have been many experiments on productivity by psychologists who focus on work, and generally, they have determined that people can only do four or five hours of productive work per day. After their performance reaches its peak, it tends to stall, and then people start to suffer. According to K. Anders Ericsson, an expert on the psychology of work, if you push people beyond the time they can really concentrate maximally, you’re going to get them to acquire some bad habits. Even worse, those bad habits will make their way into the time when they are normally productive (1).
32 hour work week
Ryan Carson, CEO of Treehouse, instituted a 32 hour work week back in 2006, and ever since his employees have been happy and more productive, all the while his company makes millions of dollars in revenue. In a similar case, Reusser Design switched to a four-day work week in 2013 and the company founder, Nate Reusser, says his employees’ performance is much higher (1).
Giving up just one day of work
In a survey published in the monthly labor review, twenty-eight percent of respondents stated that they would give up one day worth of pay for one extra day off from work. But not only do people prefer having an extra day off but productivity actually suffers the longer you work (4). In a 2014 paper from Stanford University, they found that results start to slide around the 50-hour per week mark, in that people were producing less (5). In another study, by the Families and Work Institute, people who feel overworked said they make more mistakes at work (6). So not only does productivity fall at a certain point but mistakes are made, further compounding productivity.
Making mistakes at work
In a study done on nurses who worked long hours, the relationship between work duration and adverse events and errors was calculated. Researchers determined that adverse events and error variables were significantly related to working more than 40 hours in the average week. Small tasks relating to medication and needlestick injuries had the strongest and most consistent relationship with the work hour and voluntary overtime variables (7).
Overworking and depression
Not only does productivity fall when we are overworked but our health begins to suffer as well. In a study done in Japan of small and medium sized businesses, It was found that participants who worked ten hours per day and slept only six hours per night reported up to ninety-seven percent more chance of depression when compared to those who worked only six to eight hours a day (8).
Theorists have often contemplated that our work week would become shorter and shorter the more we became technologically capable. But that appears not to be the case, the standard forty hour work week is the norm in many companies, but is it really contributing to overall productivity? It seems we have a limit to how productive we can be, our attention to detail starts to fail us and mistakes are made. A four-day work week can benefit both our state of minds and our health.
