During World War II, the rush to produce munitions in sufficient quantities to fight the Germans led the British to run factories 24 hours a day and to keep workers on for heroic work weeks of 70 hours or longer. More! faster! was the demand from leaders. Ironically though, working longer simply doesn’t equate to greater productivity, no matter what managers believe. The Economist reports that a recent analysis of data from the period reveals worker productivity declined steadily once past 52 hours of work. A more recent study of call-centre workers confirms the effect, showing that call times lengthen and fatigue increases as work hours go up. Working longer actually harms output.
Of course, harm is not simply limited to productivity. An enormous study of over 500,000 men and women published in the Lancet found that working longer reliably increased the risk of stroke by nearly 1/3 for working more than 55 hours per week. In Japan, death caused by overwork has long been a problem and even has a name: karoshi. Despite Japanese government policies and programs to reduce the pressure to work longer and faster, numbers haven’t changed significantly. It seems that managers and workers find it hard to imagine that reducing working time can help productivity—or at least, not cause it to decline.
Even worse, managers can’t reliably tell who is really working during those longer hours, or those who are engaging in presenteeism (that is, they are there, but not really doing anything).
Researcher Erin Read noted that men and women tend to deal with the expectations of needing to be ‘always on’ in quite different ways. Women tended to make formal accommodations, such as reducing their work hours, even though that means they become marginalized within the firm. On the other hand, men found unobtrusive, under-the-radar ways to alter the structure of their work so they could work predictable schedules in the 50- to 60-hour range.
Leaders need to understand that for work that is largely self-directed, and which requires intellectual engagement, time is poorly correlated with productivity. You may achieve more in an hour of hard work than in just being in the office. Indeed, this point convinced a New Zealand insurance company to trial a 4-day work week for all staff, for the same pay. The three-month experiment revealed that job and life satisfaction increased both at home and work, and employees performed better in their jobs. So successful was it, that the change has been made permanent.
Leaders can exert a significant impact on staff wellbeing, obviously through their leadership, but also by modelling good self-care themselves. Research-based hacks can still mean that you can slow down, deliver the same or better outputs, and improve your wellbeing at the same time.
But the first task is to get over the addiction of being busy.
We also know that the brain chemistry that occurs with being busy is both compelling and hard to resist. Being busy drives a surge of both dopamine and adrenaline into our system. These hormones create something like an addictive effect—it feels great and so we crave more of it. That’s all good in the short term. Long term, though, that rush of dopamine and adrenaline leaves us feeling depleted. In direct contrast to this depletion affect, the work of Professor Sabine Sonnentag has shown that detaching from work, slowing down, and engaging in enjoyable off-job activities greatly improved people’s moods and productivity the following day.
Consistent scientific research has shown that we experience less fatigue and maintain stronger wellbeing when we experience stress or challenge for specific periods of time, then balance this effort with active recovery (when we purposefully recharge our mental and physical batteries). Oscillating between periods of challenge and periods of recovery is ideal, with planned and regular recovery as optimum.
When you need immediate recovery, try:
Remember, if you feel like you are too busy to take a recovery break, it’s a definite sign you need one!
