Mental Health at Work: How to Measure It and Take Action
Companies are investing in employee well-being surveys, mental health programs, and workplace initiatives. But one question deserves more attention: Do we actually know what we're measuring and what to do with the results?
One employee says everything is fine. Another admits to feeling overwhelmed. A third doesn't respond to the survey at all.
A few weeks later, someone resigns. Another employee takes an extended leave. And a manager discovers that the team's workload has been unsustainable for months.
Could the warning signs have been spotted earlier?
Possibly. But only if someone had been looking at the right things.
Organizations have no shortage of workforce data. Engagement scores, employee satisfaction, absenteeism, turnover, burnout indicators, and workplace culture surveys have become familiar features of modern HR dashboards.
Yet these metrics don't all tell the same story.
And collecting them doesn't automatically tell us what to do next.
----------
First, What Do We Actually Mean by Mental Health at Work?
Mental health is more than the absence of a mental health condition.
The World Health Organization (WHO) describes it as an essential part of health and well-being, influencing our ability to cope with life's challenges, learn, work, and contribute to society.
In the workplace, however, three related concepts are frequently treated as though they mean the same thing.
Individual mental health refers to a person's psychological well-being. It can be influenced by professional, personal, social, and medical circumstances.
Workplace well-being describes people's experience of their working environment, including their sense of support, autonomy, recognition, relationships, and ability to perform their jobs under reasonable conditions.
Psychosocial risks are aspects of work and how it is organized that can negatively affect health. These include excessive workloads, limited control over tasks, workplace conflict, bullying, unclear responsibilities, and poorly managed organizational change.
These concepts overlap, but they aren't interchangeable.
Someone can genuinely enjoy their job while struggling with an excessive workload.
A team can report high satisfaction while routinely working unreasonable hours.
And an employee living with a mental health condition can thrive in a workplace that provides appropriate support.
That distinction matters.
An employer's responsibility isn't to diagnose employees. It's to understand and address the workplace conditions that may put their health at risk.
----------
Why Good Intentions Aren't Enough
According to the WHO, approximately 15% of working-age adults were living with a mental disorder in 2019.
Globally, depression and anxiety are estimated to account for 12 billion lost working days every year, representing approximately US$1 trillion in lost productivity.
These figures don't suggest that work causes every mental health condition. They illustrate the enormous intersection between psychological health and working life.
Still, many workplace initiatives focus more on helping employees cope with difficult conditions than on examining those conditions themselves.
Stress management workshops. Resilience training. Meditation apps. Wellness challenges.
These initiatives may provide genuine benefits.
But they cannot substitute for addressing problems in how work is designed and managed.
Teaching breathing exercises to an understaffed team might help individual employees manage stress.
It won't solve the staffing problem.
This is one reason the WHO's mental health at work guidelines emphasize organizational interventions that seek to prevent or reduce psychosocial risks.
The goal isn't simply to help people tolerate unhealthy conditions more effectively.
It's to make those conditions healthier in the first place.
----------
How Do You Measure Something You Can't See?
One of the biggest mistakes organizations make is treating mental health as though it can be captured in a single number.
There is no universal score that reliably summarizes the psychological health of an entire workforce.
A meaningful assessment starts with a more specific question.
Are employees struggling with unreasonable demands? Are managers providing adequate support? Is uncertainty around responsibilities creating unnecessary stress? Has a recent organizational change affected how people experience their work?
The question determines what should be measured.
Six Areas Worth Examining
The UK's Health and Safety Executive (HSE) developed a widely used framework for understanding work-related stress.
Its Management Standards identify six key areas associated with workplace stress risks.
- Demands: Are workloads, deadlines, and working conditions manageable?
- Control: Do employees have sufficient influence over how they work?
- Support: Are people receiving the resources, guidance, and assistance they need?
- Relationships: Does the workplace promote respect and address unacceptable behavior?
- Role: Do employees understand their responsibilities and what's expected of them?
- Change: Are organizational changes communicated and managed effectively?
The value of this framework lies in its practicality.
Asking employees whether they're happy at work may provide useful information.
But asking whether they have enough time to complete their responsibilities properly points toward something management can actually investigate.
Both questions have a place.
They simply lead to different kinds of decisions.
----------
Should You Build Your Own Employee Survey?
Not necessarily. In fact, starting from scratch is often unnecessary.
Several established instruments are available to help organizations assess workplace conditions and employee well-being.
The HSE Management Standards Indicator Tool focuses on factors associated with work-related stress.
The Copenhagen Psychosocial Questionnaire (COPSOQ) examines a broader range of psychosocial workplace factors, including job demands, relationships, and aspects of well-being.
The NIOSH Worker Well-Being Questionnaire (WellBQ) takes a multidimensional approach, considering work experiences alongside other dimensions of worker well-being.
These instruments serve different purposes.
Choosing between them requires an understanding of what the organization wants to learn, whether suitable validated language versions are available, and how the results should be interpreted.
It's also important to consider each instrument's psychometric properties and conditions of use.
Putting together a few appealing questions from different online surveys might seem efficient.
But a questionnaire that hasn't been properly designed or validated can produce results that are difficult to interpret, compare, or act upon.
A survey is only useful when you understand what its questions are actually measuring.
----------
Anonymous Doesn't Always Mean Unidentifiable
Trust plays a central role in gathering sensitive workplace information.
Employees who worry about being identified may hesitate to report excessive demands, poor management practices, or interpersonal conflict.
But simply labeling a survey "anonymous" doesn't guarantee anonymity.
In a team of four people, a combination of job responsibilities, tenure, or written comments may make it possible to identify a respondent.
Organizations should therefore collect only necessary information, restrict access to individual responses, and avoid reporting results for groups that are too small to protect confidentiality.
Employees should also understand why information is being collected, who can access it, and how it will be used.
Trust isn't created by the survey platform alone.
It's built through the organization's behavior before, during, and after the assessment.
----------
Can HR Data Reveal Mental Health Problems?
Sometimes it can reveal warning signs.
But rarely on its own.
Absenteeism, employee turnover, overtime, reported incidents, and exit interviews may provide valuable context.
None of these indicators, however, is a direct measure of mental health.
An increase in sick leave can have many explanations.
Low turnover doesn't necessarily mean employees are thriving.
And a team consistently exceeding its performance targets may still be operating under unsustainable pressure.
The more useful approach is to look for patterns across different sources of information.
Imagine a department where survey responses point to excessive workloads.
At the same time, overtime is increasing, and employees repeatedly describe conflicting priorities during team discussions.
Together, these observations provide a stronger reason to examine how work is organized than any single metric would.
Even then, caution matters.
A workplace indicator is a signal worth investigating—not a diagnosis waiting to be assigned.
----------
The Survey Is Complete. Now What?
This may be the most important part of the entire process.
An organization launches a survey, collects responses, prepares a presentation for leadership, and thanks employees for participating.
Then everyone returns to business as usual.
Six months later, another survey arrives.
The problem may have nothing to do with the quality of the questionnaire.
It may be the absence of a clear process for turning findings into decisions.
The international standard ISO 45003 provides guidance on managing psychosocial risks through a structured approach: identifying hazards, assessing risks, implementing preventive measures, and evaluating their effectiveness as part of continuous improvement.
In other words, measurement is a starting point.
Not an accomplishment in itself.
----------
Three Problems That Call for Three Different Responses
Problem 1: Employees consistently report excessive workloads.
The first response shouldn't automatically be another stress management workshop.
Management should examine staffing levels, workload distribution, deadlines, competing priorities, and operational expectations.
Meaningful action might involve reallocating responsibilities, eliminating unnecessary tasks, or adjusting targets.
Individual stress management support can complement these changes.
It cannot replace them.
Problem 2: Employees feel unsupported by their managers.
Management training may help improve communication, active listening, and the ability to recognize when someone needs support.
But organizations should also ask whether managers have enough time, authority, and resources to support their teams.
A manager who is overwhelmed may struggle to provide meaningful support, even with the best training.
Problem 3: Employees don't understand their responsibilities.
The solution may involve clarifying roles, decision-making authority, and performance expectations.
A company-wide wellness initiative would do little to resolve that particular problem.
The lesson is straightforward.
The most appropriate intervention depends on the risk identified—not on whichever workplace wellness initiative happens to be popular.
----------
What Does the Research Actually Support?
The WHO's guidelines on mental health at work distinguish between several types of interventions, including organizational changes, manager training, worker training, and individual support.
Organizational interventions aim to reduce psychosocial risks by changing aspects of the working environment.
These may include workload adjustments, improvements to scheduling and communication, changes to management practices, and measures to prevent bullying or harassment.
The WHO recommends organizational approaches while acknowledging that the certainty of the supporting evidence varies across interventions and outcomes.
That distinction matters. A recommended practice isn't necessarily backed by equally strong evidence in every setting.
Manager training can improve managers' knowledge, attitudes, and supportive behaviors related to mental health. It may also help employees feel more comfortable seeking assistance.
This doesn't mean managers should become therapists.
Their role is to recognize potential difficulties, respond appropriately, guide employees toward suitable resources, and address workplace factors within their control.
Individual support measures, including certain psychological interventions and reasonable workplace accommodations, can also help employees who need additional assistance.
Effective prevention therefore rarely comes down to one program.
It generally involves a combination of healthier working conditions, capable managers, and access to appropriate support.
----------
What Could a 90-Day Approach Look Like?
Organizations don't necessarily need an elaborate program to begin taking workplace mental health risks seriously.
They do, however, need a clear objective, appropriate safeguards, and a commitment to follow through.
The following 90-day framework is an illustrative implementation approach—not a scientifically validated universal protocol.
Days 1–30: Understand the Situation
Start by defining what the organization wants to investigate.
Select an appropriate assessment instrument and explain the purpose of the process to employees.
Be clear about confidentiality, how results will be reported, and how findings may influence future decisions.
Collect responses and, where appropriate, complement them with organizational indicators and voluntary employee discussions.
The objective at this stage isn't to rush toward solutions.
It's to develop a reliable understanding of the problem.
Days 31–60: Make Decisions
Analyze results at an appropriate group level, protecting individual confidentiality.
Identify the most significant risks and discuss potential explanations with the people affected.
Then select a manageable number of concrete actions.
That might mean adjusting workload distribution, clarifying responsibilities, or strengthening manager support.
Each action should have an owner, a timeline, and a way to assess progress.
Two meaningful changes are better than fifteen vague commitments.
Days 61–90: Act and Check Progress
Begin implementing the selected changes.
Tell employees what the organization learned, what it plans to do, and which issues require further investigation.
Check whether the planned actions have actually taken place and gather initial feedback.
Ninety days may not be enough to demonstrate a lasting improvement in mental health or psychosocial risk levels.
Some changes take much longer to produce measurable results.
The purpose of the timeline is to ensure that the assessment leads to action—not to promise that complex workplace problems can be solved in three months.
----------
How Do You Know Whether the Changes Are Working?
An intervention can sound reasonable without delivering the intended results.
That's why organizations should decide what success would look like before making changes.
If excessive workload is the concern, relevant measures might include employee perceptions of job demands, overtime patterns, and operational difficulties.
If manager support is the issue, follow-up assessments and qualitative employee feedback may help identify whether conditions are improving.
Consistency matters. Measurements should be sufficiently comparable over time to support meaningful interpretation.
But there's another important limitation.
An improvement after an intervention doesn't automatically prove that the intervention caused it.
Changes in staffing, business activity, seasonality, or other organizational developments may also affect the results.
More rigorous evaluations can account for these factors and, where feasible, use appropriate comparison groups.
For most organizations, the essential principle remains the same:
Measure carefully. Act deliberately. Evaluate honestly. Adjust when necessary.
And communicate what has changed.
----------
Maybe We're Asking the Wrong Question
Mental health at work cannot be reduced to a score out of ten.
Behind every data point are people with different experiences, circumstances, and needs.
Organizations cannot control every factor affecting an employee's mental health.
But they can influence many aspects of the working environment: demands, autonomy, support, relationships, role clarity, and how change is managed.
They can also help create workplaces where asking for support doesn't feel like taking a professional risk.
The challenge, then, isn't to build a dashboard that claims to summarize the mental health of an entire workforce.
It's to develop the organizational ability to recognize risks, listen to employees, and change the conditions that need changing.
Because the most important question after a workplace mental health survey may not be:
"What score did we get?"
It may be:
"Now that we know, what are we going to do differently?"
