The Hidden Costs of Mental Health

Continuing to work through physical or mental strain comes at a cost that is not always immediately visible

Most workers have gone to work when they were not feeling their best. Whether due to a lingering illness, stress, fatigue, or a desire to avoid falling behind, many choose to push through.

A strong work ethic and sense of responsibility are often valued in the workplace. However, recent Canadian research suggests that consistently working while unwell may carry greater consequences than previously recognized, both for employees and for employers.

According to a recent Manulife Canada survey, 61 percent of Canadian workers report working while unwell. While absenteeism often receives the most attention in workplace discussions, the study found that presenteeism—being physically present at work but unable to perform at full capacity due to health concerns—accounts for the largest share of productivity losses in Canadian workplaces. This highlights an important reality: being present at work is not the same as being able to contribute fully.

Employees lose an average of 19 percent of their working time due to health-related productivity challenges while still on the job, compared to just 3 percent lost through absences.

Combined, this represents approximately 46 lost working days per employee each year. These numbers point to a significant but often hidden cost, affecting not only organizational performance but also the daily experience of workers themselves.

Mental health plays a central role in these losses. More than half of surveyed employees indicated that mental health challenges affect their ability to perform effectively, while 57 percent reported experiencing burnout at least some of the time.

Stress, mental fatigue, and emotional exhaustion are becoming increasingly common across many sectors. These challenges can affect focus, decision making, and relationships at work, making it harder for individuals and teams to thrive.

The broader economic impact is also substantial. The Mental Health Commission of Canada estimates that mental health problems and illnesses cost the Canadian economy more than $50 billion each year. A significant portion of this is tied to workplace productivity losses, including both absenteeism and presenteeism. This underscores that mental health is not only a personal concern but also a shared responsibility within workplaces and communities.

Beyond productivity, there are wider implications for workplace culture and long term well-being. Employees who continually push through mental health challenges may see their condition worsen over time, potentially leading to extended absences or disability. This can also affect morale, trust, and a sense of support within a workplace.

These findings point to the importance of creating work environments where people feel supported and able to speak openly about their challenges. Employers can play a meaningful role by providing access to resources, encouraging balance, and fostering a culture of care and respect. In turn, workers benefit from recognizing when they need rest or support and taking steps to address concerns early.

Ultimately, caring for mental health is part of building healthy, sustainable workplaces. When both employers and employees take this seriously, it contributes not only to stronger organizations but also to the well-being of individuals, families, and communities.
