Mental health awareness week, celebrated in May, is a momentous period dedicated to promoting mental health awareness, battling the associated stigma, and advocating for policies aiding people with mental health issues. It’s a time to focus on a domain that often doesn’t receive the mental health attention it deserves: the workplace. The impact of individual well-being on the overall health of the workplace, known as the ‘Halo Effect,’ is substantial and worth our attention.

Understanding Mental Health and Its Impact

Mental health is a comprehensive and multifaceted concept. It’s much more than the absence of mental disorders or illnesses; it’s an integral part of our overall health. The World Health Organization (WHO) defines mental health as,

“a state of well-being in which the individual realises his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community.”

Mental health encompasses everything from our emotional and psychological well-being to our social well-being. It affects how we think, feel, and behave, influencing how we handle stress, make choices, relate to others, and engage with our environments.

The impact of mental health on individuals and communities is profound. At an individual level, mental health disorders can disrupt a person’s thinking, feeling, mood, ability to relate to others, and daily functioning. On a broader scale, mental health issues can have far-reaching effects on productivity, physical health, relationships, and social cohesion.

The impact of mental health issues is not confined to those directly suffering. It also extends to their families, friends, and colleagues who may also be affected. According to Mind, a UK-based mental health charity, approximately 1 in 4 people in the UK will experience a mental health problem each year. This is a significant percentage of the population, underscoring the reach and relevance of mental health issues.

In terms of the workplace, mental health can have a significant economic impact. The WHO estimates that depression and anxiety cost the global economy $1 trillion per year in lost productivity. In the UK, mental health issues lead to an estimated 70 million lost working days annually, costing businesses approximately £2.4 billion per year, as reported by the Centre for Mental Health. These issues can lead to reduced productivity, high turnover, and substantial direct and indirect healthcare costs.

Unfortunately, despite the prevalence and impact of mental health issues, there’s still a significant amount of stigma attached to them. Many people are hesitant to seek help due to fear of discrimination or misunderstanding. This stigma can result in individuals not getting the help they need, which can exacerbate mental health issues and contribute to the cycle of mental illness.

Therefore, understanding mental health and its impact is the first step towards addressing these issues, reducing stigma, and promoting mental well-being in all aspects of life, including at work. This understanding can help create more inclusive, supportive environments where everyone feels empowered to seek help if needed and contribute their best, both personally and professionally.

The Halo Effect at Work

The ‘Halo Effect’ at work refers to the positive influence that individual well-being, particularly mental health, has on the overall work environment. This radiating impact can manifest in several ways:

  1. Increased productivity and creativity: A mentally healthy workforce is more likely to be productive and creative. Employees with good mental health can concentrate better, think of innovative solutions, and maintain a high level of energy. According to a study by the University of Warwick, happy employees are up to 20% more productive than unhappy ones.
  2. Positive work culture: Mental health significantly influences the work culture. Employees in good mental health tend to have better relationships with their colleagues, promoting a supportive and collaborative work environment. A study in the Journal of Applied Psychology found that supportive environments could reduce the impact of mental health issues on productivity by as much as 50%.
  3. Talent retention and attraction: Businesses that prioritise mental health are more likely to attract and retain top talent. According to a UK survey by Mind, 60% of employees would feel more motivated and more likely to recommend their organisation as a good place to work if their employer took action to support mental well-being.
  4. Reduced absenteeism and presenteeism: Mental health issues are a leading cause of absenteeism (not showing up for work) and presenteeism (being present but unproductive at work). Addressing mental health can reduce these issues, leading to significant cost savings. A Deloitte UK study found that poor mental health costs UK employers up to £45 billion each year, a rise of 16% since 2016, primarily due to worsening presenteeism.
  5. Improved customer service: Employees who are mentally healthy are more likely to provide excellent customer service, as they tend to be more patient, empathetic, and responsive. According to the Institute of Customer Service, there’s a clear correlation between employee well-being and customer satisfaction.
  6. Enhanced reputation: Companies that prioritise mental health are seen as socially responsible, which can enhance their reputation among consumers, potential employees, and the wider community.
  7. Better decision making: Good mental health promotes better decision making. Employees who are mentally fit are more likely to make thoughtful, strategic decisions, contributing to the company’s overall success.

In essence, the ‘Halo Effect’ of mental health at work is a comprehensive, multi-faceted phenomenon. It can influence everything from individual productivity and creativity to team dynamics, customer satisfaction, and the company’s bottom line. Prioritising mental health is not just the right thing to do; it’s also a smart business decision.

What businesses should be doing?

  1. Promoting open dialogue: Encourage discussions about mental health, making it as normal as discussing physical health. Workshops, seminars, mental health days off, and anonymous suggestion boxes can support this initiative, fostering a culture of openness and acceptance.
  2. Leadership involvement: Leaders should model healthy behaviours and ensure mental health resources are accessible. Managers should be trained to recognise the signs of mental distress and guide their team members to appropriate help. Leaders should also openly discuss their own experiences with mental health to normalise the conversation.
  3. Reassessing workplace policies: Policies should be redesigned with mental health in mind. This might mean offering flexible work hours, remote working options, and opportunities for relaxation and decompression during the workday. Paid mental health days off can also be considered.
  4. Establishing Employee Assistance Programs (EAPs): EAPs that offer resources for mental health issues can be invaluable. These can include therapy sessions, stress management programs, and resources for handling personal issues.
  5. Creating a supportive environment: A culture of understanding and empathy goes a long way in promoting mental health. Businesses should foster an environment where employees feel supported and understood when facing mental health challenges.
  6. Providing mental health training: Regular training sessions can be conducted to educate employees about mental health, signs of common mental illnesses, and ways to support colleagues who may be struggling.
  7. Implementing wellness programs: Wellness programs that focus on overall health, including physical activity, nutrition, and mindfulness, can have a positive impact on mental health. Encouraging employees to take breaks and maintain a work-life balance is also important.
  8. Regular check-ins: Encourage managers to have regular check-ins with their team members to discuss not just work-related issues but also general well-being. This can help in early detection of any potential mental health issues.
  9. Providing resources for remote workers: With the increase in remote work, businesses should provide resources and tools to help remote workers deal with feelings of isolation and burnout.
  10. Encouraging use of vacation time: Employees should be encouraged to use their vacation time to rest and rejuvenate, which can greatly benefit their mental health. It’s important to respect employees’ time off and discourage a culture of working during vacations.


The workplace is not just a place for business transactions; it’s a community of people with diverse mental and emotional needs. The halo effect of individual well-being at work is a testament to the inter-connectedness of our professional and personal lives. This Mental Health Awareness Month let’s make a concerted effort to recognise and nurture mental health in the workplace. The benefits will be manifold, reaching far beyond the office walls, enhancing the quality of life of employees and the health of our businesses.
