In its most recent study, the World Health Organization (WHO) has thrown light upon the fact that long working hours are killing hundreds of thousands of people a year in a worsening trend that may accelerate further due to the COVID-19 pandemic.

In the first global study of the loss of life associated with longer working hours, the paper in the journal Environment International showed that 745,000 people died from stroke and heart disease associated with long working hours in 2016. That was an increase of nearly 30 percent from 2000.

“Working 55 hours or more per week is a serious health hazard,” said Maria Neira, director of the WHO’s Department of Environment, Climate Change and Health. “What we want to do with this information is promote more action, more protection of workers,” she said.

Deadly impact

The joint study, produced by the WHO and the International Labor Organization (ILO), showed that most victims (72 percent) were men and were middle-aged or older. Often, the deaths occurred much later in life, sometimes decades later, than the shifts worked. It also showed that people living in Southeast Asia and the Western Pacific region, a WHO-defined region which includes China, Japan and Australia, were the most affected.

Overall, the study, drawing on data from 194 countries, said that working 55 hours or more a week is associated with a 35 percent higher risk of stroke and a 17 percent higher risk of dying from heart disease compared with a 35-40 hour working week.

Increasing risks

The study covered the period 2000-2016, and so did not include the COVID-19 pandemic, but WHO officials said the surge in remote working and the global economic slowdown resulting from the coronavirus emergency may have increased the risks.

“The pandemic is accelerating developments that could feed the trend towards increased working time,” the WHO said, estimating that at least 9 percent of people work long hours.

WHO staff, including its chief Tedros Adhanom Ghebreyesus, say they have been working long hours during the pandemic and Ms. Neira said the UN agency would seek to improve its policy in light of the study.

Capping hours would be beneficial for employers since that has been shown to increase worker productivity, WHO technical officer Frank Pega said. “It’s really a smart choice not to increase long working hours in an economic crisis.”
