Working more than 48 hours a week may be a waste of time, suggests research conducted by Stanford economics professor John Pencavel and detailed by Minda Zetlin on Inc.com. An analysis of data from British munitions factories during World War I showed that additional hours beyond 48 per week did not result in a significant increase in production. Reducing work hours for those who exceed this limit does not negatively impact productivity, according to Pencavel.
Although there are questions about the relevance of these data in today’s context, the researcher cites a series of studies that consistently support his findings.
Personal experiences validate the theory
Minda Zetlin, after facing severe burnout and reading studies like Pencavel’s, reduced her work hours and observed an increase in income and achievements. “Probably because it forced me to focus on the essentials,” she said. With a rested mind, Zetlin was able to complete essential tasks more effectively.
Two years ago, Zetlin interviewed Richard Schuster, a psychologist and TEDx speaker, who reduced his work week from 80 to 25 hours after a stroke. He reported a significant increase in productivity and profitability, as well as improvements in family relationships. “Productivity increased, profitability increased, and my relationship with my family is better than ever,” he noted.
Challenges and strategies for freelancers
Despite the benefits of limiting work to 48 hours per week, many freelancers face challenges due to client pressure. Zetlin emphasizes that freelancers are their own bosses and should act as leaders by rejecting excessive demands to preserve everyone’s well-being.
Tips for managing work hours
- Set an initial limit: Establish a time to end daily tasks and stick to it for three weeks. Note the days you succeed and don’t blame yourself when you fall short.
- Rest one full day a week: This practice, according to Zetlin, increases productivity and prepares the mind for better functioning and greater creativity.
- Prioritize essentials: Reducing work time means leaving some activities aside, which can be positive. Neuroscientist Josh Davis notes that much of what we do daily is not essential.
- Understand how you use your time: Track your activities or use online tools. For each task, ask:
– Is this activity adding value?
– Is this activity not adding value but necessary?
– Can this task be delayed with minimal consequences?
– Can this task be delegated?
After a few days, evaluate whether this approach has helped reduce your work hours to a new limit.
Regardless of how you address these issues, reducing work hours to less than 50 per week can result in greater efficiency and better job performance.
