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.

Workers with disabilities report greater OHS vulnerability
According to a new study by the Institute for Work and Health (IWH), workers who identify as having a disability are more likely to be exposed to workplace hazards. Additionally, they are more likely to face inadequate occupational health and safety (OHS) protections. “Basically, they get hit with a double whammy,” said Dr. Curtis Breslin, lead author of the study.

Workers with disabilities report greater hazard exposure and lower protection
Research elsewhere has shown that people with disabilities have a tough time getting hired. A new study at IWH now suggests we should also worry about those who do find jobs. Learn why.

Find the workers you need to protect
How do you tell which workers are vulnerable to injury? Occupational health and safety (OHS) vulnerability is not about who people are. It's about the work they do. Use the OHS Vulnerability Measure to identify workers you need to protect.

Workers with disabilities report greater OHS vulnerability
Workers with disabilities are more likely to be exposed to hazards at work than other workers, and are more likely to experience vulnerability due to inadequate measures to mitigate those hazards.
