Mental health in the workplace

Work-related psychological injuries are associated with longer durations, higher costs, and more complex return-to-work processes than physical injuries. While governments and system partners are investing in prevention and management strategies, approaches vary considerably. This project looked at how different jurisdictions in Canada and Australia prevent workplace psychosocial hazards, define and compensate psychological injuries, and support workers through recovery and return to work.

Work injury prevention and workers’ compensation agencies in Canada and Australia have a growing interest in approaches to prevent and manage work-related psychological injuries. This is due to the increasing number of these conditions, and their greater wage replacement and health-care costs compared to physical injuries. Despite this interest, there have been few formal comparative overviews of approaches taken to prevent and/or manage these types of injuries across different jurisdictions.

The objective of this project was to explore the extent to which workers’ compensation systems provide coverage for different types of psychological injuries; the strategies both workers’ compensation systems and occupational health and safety (OHS) prevention agencies adopt to address psychosocial exposures in the workplace both before and after injuries occur; and the benefits, challenges and other outcomes of each of these strategies from the perspective of those working in these jurisdictions. The findings from this project will be of interest to policy-makers in other jurisdictions, both within Canada and Australia, and more broadly.

A new report from CSA Group’s Public Policy Centre pegs the annual economic cost of poor mental health in Canada at $180 billion, a figure the authors say is likely conservative, writes Shane Mercer. The modelling used in the report, co-authored by IWH's Dr. Kathleen Dobson, focuses largely on working‑age Canadians and counts direct health and social service spending alongside lost productivity.

First responders face high rates of post-traumatic stress injuries (PTSI) due to the nature of their jobs. In response, the Workplace Safety and Insurance Board commissioned an intensive, 14-week treatment program tailored to these workers. A multi-part evaluation of the program, conducted in part by IWH, has found that participants did not show improvements in return-to-work rates. However, most participants stuck with the program for the full duration, and a quarter saw symptom improvements.

Workers who feel their workplaces are not committed to their mental wellbeing have more than twice the risk of work-related physical or mental health injuries compared to workers who feel the opposite. That’s according to an IWH study that asked workers about the psychosocial safety of their workplace—that is, whether an organization prioritizes mental health and wellbeing, and takes action to prevent psychosocial hazards. The study found that poor psychosocial safety and poor physical safety both increase the risk of work-related mental and physical injuries.
