In the high-stakes world of modern business, the mental health of employees often becomes an unseen casualty in the pursuit of productivity. Rising levels of workplace stress, anxiety, and burnout – alongside increased alcohol and drug use – pose serious challenges to companies, eroding their very foundations. As we mark International Stress Awareness Week from 4th–8th November, it’s a timely reminder for businesses to understand that employee well-being is more than a “nice-to-have”; it’s essential for sustainable success.

Lee Hawker, Clinical Director at The Cabin Chiang Mai, a leading centre for addiction and mental health treatment, observes that businesses have been slow to respond to the growing mental health crisis within the workplace. “Too many employers still treat mental health as a peripheral issue,” Hawker notes. “But the reality is, it’s central to everything. Stressed and burnt-out employees cannot perform at their best, and when mental health issues go unaddressed, they can quickly escalate into substance misuse, absenteeism, or worse.”

The invisible burden of stress

The statistics are alarming. According to the Health and Safety Executive, stress, depression, or anxiety are responsible for 57% of all working days lost due to ill health in the UK. Many employees feel that work demands are intensifying while their ability to cope is diminishing. With longer working hours, the shift to remote work, and constant connectivity, stress is no longer confined to the office; it’s everywhere.

This relentless pace has led many to seek relief through alcohol or drugs. Hawker stresses that these are not just “personal issues” but critical workplace concerns. “Managers need to understand that mental health and substance use are interconnected,” he asserts.

Health and Safety Executive data shows that 57% of all working days lost are due to stress-related illnesses, underscoring the urgent need for organisations to act.

Alcohol and drug use: a silent crisis

While the pandemic introduced more flexible working conditions, it also magnified existing mental health challenges. A recent study revealed that one in five employees admitted to drinking alcohol during working hours while working from home. While this may seem harmless to some, it points to a deeper issue: workers are increasingly using substances to manage stress, anxiety, and burnout.

“As someone who has worked in addiction recovery for many years, I’ve seen how work-related stress can drive people to use alcohol or drugs as a coping mechanism,” says Hawker. “This isn’t something employers can afford to ignore. It’s not about blame; it’s about support and early intervention.”

Research from the Institute of Alcohol Studies highlights that alcohol consumption increased among employees during the pandemic, with remote work blurring professional boundaries.

Practical solutions for businesses

While awareness of mental health issues is crucial, meaningful change only occurs when businesses create genuinely supportive environments. Hawker offers several practical steps to help companies foster mental well-being:

• Open the dialogue. Mental health remains a difficult topic for many employees to address. Employers can make a difference by creating an atmosphere where mental health is openly discussed, similar to physical health. Leaders play a crucial role in normalising these conversations.
• Spot the warning signs. Managers must be equipped to recognise early signs of stress, anxiety, or substance misuse in their teams. The indicators can be subtle: missed deadlines, disengagement, or mood swings. These signs should not be ignored.
• Offer real support. Employee assistance programmes (EAPs), access to confidential counselling, and flexible work arrangements are essential resources for stress management. Employees struggling with personal challenges need these tools to remain productive and resilient.
• Rebuild a healthy culture. Beyond individual support, fostering a balanced workplace culture is critical. Workloads should be manageable, and deadlines realistic. A healthy workplace is one where people feel challenged but not overwhelmed.

Substance use policies: support over punishment

For many businesses, handling substance misuse is sensitive. Traditional policies often lean towards punishment, but Hawker advocates a shift towards supportive frameworks. “It’s not about policing employees,” he explains. “It’s about creating pathways for those who need help without the fear of losing their job. A punitive approach only drives the problem underground.”

“Addiction doesn’t develop in isolation,” Hawker adds. “It’s linked to stress, trauma, and mental health challenges. By offering support rather than punishment, businesses can save employees’ careers and often their lives.”

The role of managers in preventing burnout

Managers are pivotal in spotting early signs of burnout or substance use. Yet many lack the training or confidence to address these issues. “Managers don’t need to be mental health experts,” reassures Hawker, “but they should know how to listen, recognise when something’s wrong, and guide employees towards available support. Encouraging work-life balance, offering mental health days, and avoiding overwhelming workloads are key responsibilities.”

Research from Deloitte UK reveals that businesses investing in mental health interventions see substantial returns, with £5 gained for every £1 spent.

Turning awareness into action

During International Stress Awareness Week, businesses have a prime opportunity to reassess their role in supporting employee well-being. It’s time for companies to move from mere awareness to action.

Employees are the backbone of every organisation, and their mental health should never be an afterthought. By fostering a supportive environment and offering resources to help manage stress and substance use, businesses can create a culture that is not only compassionate but also resilient.
