Les travailleurs exposés à des dangers sans protection adéquate courent un plus grand risque de blessure et de maladie. Les actions des superviseurs ont également été associées à un risque de blessure. Cette étude a examiné l’interaction entre le soutien à la sécurité de la part des superviseurs et la vulnérabilité en matière de santé et de sécurité au travail sur les lésions et les maladies professionnelles.
Abstract
Background
Workers exposed to hazards without adequate protections are at greater risk of injury and illness. Supervisor activities have also been associated with injury risk. We examined the interplay between supervisor safety support and occupational health and safety (OHS) vulnerability on workplace injury and illness.
Methods
A survey was administered to 2,390 workers employed more than 15 hrs/week in workplaces with at least five employees who had a direct supervisor. We examined the combined effects of hazard exposure with inadequate protection (OHS vulnerability) and supervisor support on workplace injury and illness, using additive interactions in log-binomial regression models.
Results
OHS vulnerability and lack of supervisor support independently increased the likelihood of physical injuries at work. Crude and adjusted models showed that the risk of physical injury was at least three and a half times higher among those experiencing both OHS vulnerability and a lack of supervisor support compared to individuals without OHS vulnerability and with a supportive direct supervisor. Workers who experienced vulnerability were less at risk if they had a supervisor who was supportive.
Conclusion
In workplaces where workers experience one or more types of OHS vulnerability, having a supportive supervisor may play an important role in reducing the risk of injury and protecting workers.
