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.

Protecting minds a priority in changing times

In a world where the only constant is change, mental health has become the fastest-growing category of disability in the workplace, Marcel Van der Wier writes. And yet, society is still taking an overly individualistic approach to mental health, emphasizing employee resilience instead of focusing on structural problems in the way work is organized, says Institute for Work & Health's Dr. Peter Smith.
