Cet article examine les effets des conditions inadéquates de travail et de santé et de sécurité sur le risque de blessures chez les travailleurs, ainsi que la façon dont ces facteurs interagissent. Cette étude a été menée auprès de 2803 adultes travaillant 15 heures ou plus par semaine dans les provinces de l’Ontario, la Colombie-Britannique et l’Alberta.

Background Employment standards (ES) include having a regular payday, regular breaks, the right to paid sick or vacation time, and paid wages. Inadequate ES contribute to the labour market vulnerability of workers; however, they are not typically considered to be risk factors for workplace injury. In a sample of Canadian workers, we examine the risk of injury associated with inadequate ES, independent of, and combined with inadequate workplace protections from workplace hazards. Methods Data from 2,803 adults working 15 hours or more/week in workplaces with at least five employees were analysed. We explored associations between exposure to workplace hazards with inadequate protections [termed occupational health and safety (OHS) vulnerability] and inadequate ES on workplace injury (physical or mental injury; injury requiring time off). Additive interaction models were used to examine the independent and combined effects of these exposures. Results Occupational health and safety vulnerability and inadequate ES were independently associated with increased injury outcomes. Adjusted models showed an additive relationship for all injury outcomes between OHS vulnerability and inadequate ES. Statistically significant superadditive relationships were observed for physical injury risk with policy and procedure vulnerability plus inadequate ES [synergy index (S) 1.50, 95% CI: 1.13–2.00] and for overall OHS vulnerability plus inadequate ES (S 1.53, 95% CI: 1.16–2.02), suggesting a combined effect greater than independent effects. Conclusion Occupational health and safety vulnerability and inadequate ES are independently associated with workplace injury. For certain injury outcomes, the combined effect of OHS vulnerability and inadequate ES is greater than the independent effects of each individual exposure.
