Workplace OHS programs and practices

Workplaces play a vital role in ensuring the well-being of workers. So knowing what occupational health and safety (OHS) practices are most effective in preventing injury and illness is essential. The Institute for Work & Health (IWH) has a long history of conducting workplace-based research to provide practical guidance to employers, workers, OHS professionals and regulators about what works and what doesn’t. This research targets the injury and illness prevention practices of workplaces, as well as the programs developed by governments, health and safety associations and others to support and motivate workplaces in adopting effective practices.

New resource to help workplaces implement MSD prevention programs

Workplaces currently use a range of practices to prevent musculoskeletal disorders (MSDs)—from ergonomics training and workstation adjustments to work redesign. To help workplaces identify and implement appropriate prevention programs, a research team at IWH worked with partners in Newfoundland and Labrador to create a resource that draws upon the best available research evidence, integrated with practitioner expertise and stakeholder experiences. The resource is now available to download.

Issue Briefing examines role of workplace COVID outbreaks in Ontario’s second wave

In the current second wave of COVID-19 in Ontario, workplace outbreaks—not including outbreaks in health-care, congregate living (e.g. correctional) and educational settings—represent slightly over five per cent of all cases among working-age adults, down from a high of 22 per cent in June. That’s according to an analysis by IWH Scientific Co-Director Dr. Peter Smith and President Dr. Cam Mustard, detailed in a new Issue Briefing.

The “union safety effect” in Ontario’s construction sector: study update

Five years ago, a study conducted by IWH compared work-related injury rates between unionized and non-unionized companies in Ontario’s institutional, commercial and industrial (ICI) construction sector. It found unionized companies had lower rates of lost-time injury claims than their non-unionized counterparts, after accounting for other factors like company size. Is this “union safety effect” still holding true? On Tuesday, January 12, Dr. Lynda Robson shared an update at an IWH Speaker Series presentation. The full report of that study is now available.
