The dangers of working long hours

Fatigue can lead to a host of health problems and increases the chance of a workplace injury.

When one thinks about a dangerous workplace, it’s common to picture employees using heavy equipment, working from heights, wielding sharp tools, etc. But there’s one risk that has led to an increase in deaths over the last several years: working long hours.

The trend to work long hours, or over the standard 40-hour workweek, has been on the rise for many years. And with the increase in people working from home throughout the COVID-19 pandemic, working longer hours has steadily become the norm. Around 9% of the global population works at least 55 hours a week.

OSHA reports that along with irregular and extended shift work, long work hours can lead to fatigue and physical and mental stress. Fatigue is the feeling one gets when rest is severely needed, and it can cause:

Fatigue can also lead to an array of health problems, from heart disease and musculoskeletal disorders to depression and poor eating habits. Additionally, when employees are fatigued, they are at an increased risk for illnesses and injuries.

What happens when working long shifts? 

The World Health Organization (WHO) conducted a study with the International Labor Organization (ILO) that analyzed death and health associated with working long hours. Between 2000 and 2016, there was a 29% increase in deaths from stroke and ischemic heart disease tied to long work hours. Working 55 hours or more a week is associated with an estimated 35% higher risk of a stroke and a 17% higher risk of dying from ischemic heart disease compared to those working 35-40 hours per week.

These findings are startling, and other studies have confirmed the dangers of working long hours or extended shift work. In particular, it’s reported that employees who work extended shifts are 2.3 times more likely to report a car crash and 5.9 times more likely to report a near-miss accident.

The impact is especially true for those with shift work sleep disorder (SWSD), a condition that commonly affects individuals who work night, early morning or rotating shifts along with longer than normal hours. SWSD occurs when the circadian rhythms that regulate the sleep-wake cycle become misaligned. Those with shift work sleep disorder often suffer from insomnia, recurring sleep loss and excessive sleepiness when awake. The condition can impact work performance and put workers at a higher risk of accidents, both on-the-job and vehicular, as reaction time and alertness are greatly decreased.

Keeping employees safe from these dangers 

Longer hours lead to both physical and mental fatigue and errors. Through some basic steps, employers can greatly reduce the impact of fatigue. OSHA offers prevention tips for employers to help employees avoid fatigue and the dangers associated with working long hours. These include:

The current labor shortage is heightening the dangers of working longer hours. Often the employees who are being asked to work the longer hours now lack the requisite skills and training that they might be able to fall back on in their fatigued state, and this can lead to very dangerous situations.

Employees working long hours or extended shifts should take extra care to ensure a healthy sleep cycle. OSHA recommends:
