Mental health in the workplace

Workplaces play a dual role in the area of mental health. On the one hand, they can be a stressful environment that contributes to mental health problems among workers. On the other hand, they can play an important part in helping to detect and manage mental health problems when they arise among workers, and in ensuring the healthy recovery and return of workers who are off work due to a mental health issue. IWH research in this area helps paint a clearer picture of the prevalence of mental health problems among workers, the types of labour force and workplace factors that may contribute to poor mental health, and the workplace-based and system prevention efforts that can help improve the mental health of workers and ensure they have the proper supports when needed.

PTSI treatment program delivers benefits for first responders, but no change in return-to-work rates

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.

Lower injury rates found when workers feel their workplace prioritizes their wellbeing

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.

Mental health of Canadians who work from home no better or worse than those working outside the home

Canadian adults who work from home report the same levels of mental health, life satisfaction and stress as those who work on-site at a workplace, or at no fixed location (on the road). That’s according to a study of survey data from almost 25,000 Canadians in 2022, after work-from-home arrangements became more common.
