Our findings help identify workplaces that have higher risks of COVID-19 outbreaks, such as workplaces with high on-site worker counts, that employ temporary foreign workers, that employ staff who have contact with clients or that are localized in an urban setting. This information is instrumental in better addressing occupational hazards and risks. Objectives: The aims of the studies are to describe COVID-19 outbreaks in the workplaces of the Monteregie Region, Quebec, Canada, and to evaluate potential risk factors for identifying at least one COVID-19 outbreak in these workplaces. Methods: An ecological retrospective cohort study was conducted using deidentified databases of COVID-19 outbreaks that occurred in workplaces from February 27, 2020, to June 30, 2021. Results: Among 30,489 workplaces studied, 897 workplaces with at least one COVID-19 outbreak were identified. These outbreaks were associated with a sizeable number of workers in the workplace (adjusted odds ratio [aOR] = 6.78; 95% CI: 5.43–8.47), the presence of temporary foreign workers (aOR = 2.26; 95% CI: 1.53–3.33), contacts with clients (aOR = 1.93; 95% CI: 1.68–2.21), and being localized in the Montreal Metropolitan Area (aOR = 1.26; 95% CI: 1.09–1.45). Conclusions: These results enable the identification of potential risk factors for COVID-19 outbreaks in workplaces, with the aim of targeting workplaces where infection control and prevention measures might be enhanced or adapted to improve workers' health.

Objective: To test a model of presenteeism on the basis of established and emerging theories separated into organizational and individual factors that could be mediated by psychological distress. Methods: This was a Web survey of 2371 employees (response rate of 48%) of a provincial government agency. We assessed theories with validated measures for organizational and individual factors. Results: Psychological distress was negatively associated to presenteeism, when controlling for sex, short-term work absence in the last year, and social desirability. Both individual and organizational factors were related to psychological distress. The most important factors included the presence of stress events in the preceding 6 months, extrinsic efforts (interruptions, work requirements), self-esteem as a worker, and internal amotivation. Conclusions: By identifying modifiable factors, our results suggest that the implementation of a work organization structure that promotes stimulation and accomplishment would reduce psychological distress and further presenteeism.
