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.

Is precarious employment an occupational hazard?

Precarious employment has become more common in the Canadian labour market, as well as in the labour markets of other high-income countries. In this presentation, Dr. Faraz Vahid Shahidi examines the consequences of precarious employment for health and safety at work. Drawing on compensation claims data from the Workplace Safety and Insurance Board and labour force estimates from Statistics Canada, Dr. Shahidi asks whether workers exposed to precarious employment – such as temporary, part-time, and low-wage jobs – are more likely to experience an occupational injury or illness. As a further source of evidence, he also assesses the impact of precarious employment on the workplace transmission of COVID-19.

Lesbian, gay and bisexual workers in Canada more likely than straight workers to report low quality, precarious jobs

Drawing on a survey of Canadian workers, a recent study found that lesbian, gay and bisexual workers reported lower job quality than their straight counterparts. That’s according to a study co-led by an IWH researcher and IWH Syme award recipient, the most comprehensive study to date of job quality among sexual minority workers.

Inadequate employment standards, OHS vulnerability add to higher injury risks

IWH researchers found workers whose jobs fail to offer minimum employment standards are at an increased risk of work injury. When these workers also face health and safety vulnerability on the job, their risk of injury is even higher than the combined risk.

Unemployment benefits linked to lower mortality rates over 10 years: IWH study

We know that being out of work puts people at risk of short- and long-term health consequences—including higher death rates. A new study looks at whether—and how much—having income support during unemployment can lessen the negative impact.

Weaker OHS procedures, policies explain small employers’ higher injury risks: study

Workers at small firms are more exposed to hazards and report more work-related injuries and illnesses. But an IWH study finds injury risks in large and small firms even out when weaker OHS policies at small firms are accounted for.

Transitioning to the future of work: an intersectional study of vulnerable youth and young adults

This project applies an intersectional theoretical framework to explore the impact of the future of work on the transitional work experiences of vulnerable groups of young people—including women, visible minorities, immigrants, LGBTQ2+, and those with low socioeconomic status—and to uncover the overlapping structures that contribute to labour market inequities for different groups.

Is precarious work more prevalent for people with disabilities? The role of age and job tenure

Workers with disabilities are no more likely than those without to work in precarious jobs. However, some subsets of people with disabilities are more likely to work in precarious jobs—older people or people with shorter job tenure. Contrary to expectation, younger people with disabilities are not more likely than older people with disabilities to have precarious jobs. Among people with and without disabilities, having better health is linked to a lower likelihood of working in precarious jobs.
