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.

Increased OHS vulnerability linked to higher rates of self-reported injury: study
Workers who report being vulnerable because they are exposed to job hazards from which they are not adequately protected by workplace policies, awareness programs or empowerment mechanisms also report much higher rates of work-related injury.
