Work precarity and vulnerability

“Precarious” is a word often used to describe work that is characterized by low pay, low job security and little protection. “Vulnerable” is a word often used in the health and safety world to describe those who are at an increased risk of work injury or disease. At the Institute for Work & Health (IWH), an evidence-based framework has been developed that defines OHS vulnerability as being exposed to hazards without having adequate protection. This page pulls together research on OHS vulnerability and work precarity.

Canadian study links job quality to 'deaths of despair’

Compared to those in standard employment, workers in precarious jobs are more than three times as likely to die from drug poisoning and nearly twice as likely to die from alcohol-related causes. The risk of suicide is also markedly higher—2.4 times greater for women and 1.7 times greater for men in precarious work, reports Shane Mercer, based on a webinar presentation by IWH associate scientist Dr. Faraz Vahid Shahidi. The findings challenge the notion that having any job is enough to safeguard health, instead pointing to job quality as a critical, and often overlooked, determinant of life expectancy.

Good jobs, bad jobs, and ‘deaths of despair’

Life expectancy is stalling in Canada and other high-income countries. These trends are partly due to rising “deaths of despair,” a term that some researchers use to describe suicide, drug poisoning, and alcohol-related mortality. In this presentation, Dr. Faraz Vahid Shahidi examines the link between job quality—whether one has a “good” or “bad” job—and deaths of despair in the Canadian workforce. He asks whether people in precarious employment, which is insecure and unrewarding, are more likely to suffer an early death due to suicide, drug poisoning, or alcohol-related causes. He also discusses the role job quality can play in improving population health and stemming the rise of deaths of despair.

Precarious jobs linked to suicide, drug poisoning, and alcohol-related deaths: IWH study

In Canada and other high-income countries, rates of suicide, drug poisoning, and alcohol-attributable mortality—sometimes referred to as “deaths of despair”—have increased over time. An IWH study investigated whether job quality—measured in terms of employment stability, hours and wages—is linked to these causes of deaths.

Higher risk of work injuries found among those in precarious jobs: IWH study

Workers in jobs where precarious employment conditions are more common are more likely to experience a work-related injury or illness in Ontario, including COVID-19. That’s according to a pair of studies authored by Institute for Work & Health (IWH) researchers that examined whether employment conditions—for example, temporary contracts, involuntary part-time hours, irregular schedules and low wages—may be linked to the rate of work injuries.
