Hi. My name is Mary and I used to be a workaholic.
Ever since I can remember, I would spend endless hours “doing.” First it was school projects, then work projects for my employer, and then in the 1980s when I started my own business, I spent endless hours working in, on, and for my business. And somewhere in between, I also spent countless hours volunteering for various associations, this on top of my already full work and family schedules. Why am I telling you this? Because along the way, I learned from experience and research that being a workaholic is not only counterproductive, but it can ultimately kill you or, at the very least, make you very tired and maybe even very sick. Here’s what else I learned.
Working more than 35 to 40 hours a week does not contribute proportionally to your productivity. In fact, studies have shown that industrial workers that worked eight-hour days produced the same amount of widgets as those that worked 10-hour days. However, occasional overtime can yield results, but the gains won’t be directly proportional to the time worked. For example, if the work week is extended by 50 percent, say from 40 to 60 hours, there would only be a 25-30 percent increase in productivity. This is because people typically do their best work between hours two and six of an eight-hour work day. After that, fatigue may affect productivity. In addition, if overtime is sustained over a long period of time, fewer productivity will result because of sustained mental exhaustion.
It turns out that factory workers may be able to turn out a fairly productive eight-hour day; whereas, knowledge workers are not as productive. Productivity for knowledge workers maxes out at about six hours a day (not eight). On top of this, research by the US military has shown that cognitive decline is equivalent to a .10 blood alcohol level with even just one hour less sleep per night. What this means is that if you’re not getting enough sleep, regardless if you’re a factory or knowledge worker, you may be making the same quality decisions as a person who is inebriated. Think about that the next time you show up for a full day’s work when you didn’t get quality sleep the night before.
Workaholics be aware: you are doing yourself and your organization a disservice. You will be far more productive sticking to a 35-to-40 hour work week. If you’re having difficulty adjusting down, speak to a coach or therapist and get back on track to getting your life back. You’ll be glad you did.
