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.

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.
