Key takeaways:

• Mental health in the workplace is a business issue, not just a personal issue. 
• Stress-related absenteeism often starts with poor job design, unclear roles, weak support and unmanaged workloads. 
• Australian employers need to manage psychosocial hazards just like other work health and safety risks. 
• Small changes made early can cut sick leave, improve focus and help teams stay at work. 
• The best results come when leaders, HR and workers all share responsibility for a mentally healthy workplace.

Introduction

Mental health in the workplace affects attendance, performance, staff turnover and team culture. It also affects how safe people feel when they speak up, ask for help, or admit that their workload is no longer manageable. In Australia, one in five people aged 16 to 85 had a 12-month mental disorder in the 2020 to 2022 National Study of Mental Health and Wellbeing. That means almost every workplace already has people managing anxiety, depression, trauma, burnout, or other mental health challenges while trying to do their jobs. 

At the same time, the cost of doing nothing is steep. Safe Work Australia reports that mental health condition claims made up 12 percent of all serious claims in 2023–24 and the median time lost from work for these claims was almost five times that of all other injuries and diseases. That gap matters. It shows that mental harm at work often leads to longer absences, harder recoveries and more pressure on the rest of the team. 

This is why employers cannot treat stress as “just part of the job”. Under Australia’s model work health and safety framework, psychosocial hazards must be managed like other workplace risks. Safe Work Australia’s model code gives practical guidance and Comcare notes that the 2024 Commonwealth code identifies 17 psychosocial hazards. 

So what does a mentally healthy workplace look like in practice? It looks like clear roles, fair demands, useful support, respectful leaders, safe reporting pathways and systems that stop problems before they become claims, conflict, or long periods away from work.

Why mental health in the workplace matters

Many leaders still see workplace mental health as a wellbeing add-on. That view is too narrow. Mental health shapes how people think, decide, communicate and cope under pressure. When stress stays high for too long, work quality drops. So does concentration. People make more mistakes. Tension rises. Sick leave grows. Then the team spends more time covering gaps than doing its best work.

The global picture tells the same story. The World Health Organization says depression and anxiety lead to the loss of about 12 billion workdays each year worldwide. WHO also states that poor mental health at work can drive lower performance, absence and higher staff turnover. 

For Australian employers, the message is direct. A mentally healthy workplace helps people stay well and stay at work. A harmful workplace does the opposite.

What happens when mental health is ignored

Workplace issue	What it often leads to
Heavy workload with no control	Stress, burnout, errors, sick leave
Poor role clarity	Confusion, conflict, anxiety
Weak manager support	Isolation, disengagement, low trust
Bullying or unfair treatment	Distress, complaints, turnover
Constant change with little communication	Fear, fatigue, resistance
Exposure to traumatic content or events	Psychological harm, longer recovery time

What causes stress-related absenteeism

Stress-related absenteeism rarely comes from one bad day. It usually builds over time. Someone starts work tired. They push through. Then deadlines tighten, staffing stays lean, a manager changes, priorities shift and support drops. After that, concentration slips, sleep gets worse and even small tasks feel hard. A day off turns into a week. Then the business loses knowledge, momentum and trust.

Safe Work Australia and Comcare both point to psychosocial hazards as the work factors that can cause psychological or physical harm. These include high job demands, low job control, poor support, poor change management, poor recognition, remote or isolated work, bullying, violence and exposure to traumatic events or material. 

Common drivers of poor mental health at work

Psychosocial hazard	Example in a real workplace
High job demands	Too much work, not enough time, no recovery periods
Low job control	Staff have no say in pacing, methods, or priorities
Poor support	Managers are unavailable or only respond in crisis
Low role clarity	Workers do not know what success looks like
Poor change management	New systems or restructures announced late
Poor organisational justice	Decisions feel unfair or inconsistent
Bullying or aggression	Repeated humiliation, threats, or hostile behaviour
Traumatic exposure	Frontline, care, emergency, compliance, claims, or media roles

The signs your workplace may already be under strain

Many teams miss the early warning signs because they look normal at first. Someone goes quiet in meetings. Another person becomes sharp or withdrawn. A top performer starts missing deadlines. Managers may call it attitude, motivation, or poor resilience. Yet the real issue may be overload, poor recovery, or a culture where people feel unsafe speaking up.

Warning signs leaders should not ignore

• Rising unplanned leave 
• More frequent Monday or Friday absences 
• Increased staff turnover 
• Complaints about workload or manager behaviour 
• More conflict between team members 
• Lower quality of work 
• Slow decision-making 
• Staff disengagement in meetings 
• Presenteeism, where people show up but struggle to function 
• Higher use of employee support services after major change 

These signs do not prove a mental health condition. Still, they do show that the work environment needs attention.

Strategy 1: Treat psychosocial risk like any other safety risk

This is the starting point. If your workplace already manages physical hazards through risk assessment, controls, reporting and review, you can use the same structure for psychological risk.

Safe Work Australia states that under the model WHS laws, a person conducting a business or undertaking must manage psychosocial hazards in the workplace. The model code gives practical steps on how to identify hazards, assess risk, control risk and review controls. 

A simple four-step risk process

Step	What to do
Identify hazards	Review surveys, leave data, complaints, exit feedback, incident reports
Assess risk	Look at frequency, severity, who is affected and when the risk is highest
Control risk	Change the work, not just the worker
Review controls	Check if the fix is working and adjust it

This matters because a yoga class will not fix unsafe workload design. A meditation app will not fix bullying. An R U OK? message will not fix chronic under-resourcing.

Strategy 2: Design work that people can actually sustain

Good job design is one of the strongest ways to reduce stress-related absenteeism. When work is realistic, clear and fair, people cope better. They also recover faster after busy periods.

Practical job design changes

• Set realistic deadlines based on actual capacity 
• Limit after-hours contact unless the role truly requires it 
• Clarify what matters most this week, not just “everything” 
• Build recovery time after peak periods 
• Rotate high-stress tasks where possible 
• Give staff more say in how work gets done 
• Review staffing levels before launching new projects 
• Cut duplicate reporting and low-value admin 

For example, if a team is missing targets, the answer may not be more pressure. It may be fewer competing priorities, clearer ownership and one less report every Friday.

Strategy 3: Train managers to prevent harm, not just respond to it

Managers shape the daily experience of work. They influence pace, support, fairness, feedback and whether people feel safe. So if managers are not trained in mental health conversations, workload planning and early intervention, the whole system becomes reactive.

Beyond Blue’s mental health at work resources focus on practical tools to help create mentally healthy workplaces and support wellbeing at work. 

What managers need to learn

Skill	Why it matters
Having safe check-ins	People are more likely to speak early
Spotting early changes	Small issues can be handled before leave grows
Planning workload	Teams burn out less when demands are visible
Giving clear feedback	Uncertainty drops when expectations are plain
Responding to distress	Workers feel supported, not judged
Referring well	Managers know when to involve HR, EAP, or external care

A simple manager check-in can help:

• How is the workload feeling this week? 
• What is getting in the way? 
• What should we stop, delay, or hand over? 
• What support would help right now? 

Strategy 4: Build a culture where speaking up feels safe

A policy on paper is not enough. Workers need to believe that speaking up will lead to support, not punishment. That takes trust. It also takes consistency.

Psychological safety grows when leaders:

• ask questions without blame 
• admit pressure points openly 
• respond to concerns quickly 
• protect confidentiality 
• follow through on agreed actions 
• avoid rewarding overwork as a badge of honour 

Think about the messages your workplace sends every day. Do leaders praise people for taking breaks, using leave and setting boundaries? Or do they praise late-night emails and “pushing through”? Culture lives in those details.

Strategy 5: Support early help-seeking

People often delay help because they do not want to look weak, unreliable, or difficult. So the workplace needs to make support easy to find and normal to use.

Support options that can help

Support type	Best use
Employee Assistance Program	Short-term counselling and practical support
Mental health first aiders	Early peer support and signposting
HR support	Adjustments, leave, reporting pathways
GP or psychologist referral	Clinical care outside the workplace
Return-to-work support	Gradual recovery and safe duties
Peer networks	Connection and reduced isolation

Also, support should not begin only after someone goes off work. Early action is cheaper, kinder and more effective.

Strategy 6: Manage change better

Poorly managed change is a common source of stress. Restructures, new systems, changing rosters, mergers and role redesign can all raise anxiety when staff do not know what is happening or why.

Good change practice

• tell people what is changing and what is not 
• explain the reason in plain language 
• give clear dates 
• name who will be affected 
• invite questions early 
• brief managers before the wider team 
• provide training before new demands start 
• keep checking impact after launch 

Change itself is not always the problem. Unclear change is often the problem.

Strategy 7: Use data to find pressure points

You do not need a huge analytics team to spot mental health risks. Most workplaces already hold useful clues. The key is to look at them together.

Useful data sources

• sick leave and carers leave trends 
• workers compensation claims 
• turnover by team or manager 
• EAP usage themes 
• pulse survey results 
• exit interview feedback 
• grievance and complaint data 
• overtime patterns 
• injury and incident reports 

If one business unit has high turnover, high leave and repeated complaints about workload, that is not random. It is a signal.

Strategy 8: Create a solid return-to-work process

When someone takes leave for mental health reasons, the return to work needs care. A rushed return can make things worse. A vague return can also fail.

Safe Work Australia’s latest data shows just how serious these claims can become, with much longer median time lost than other injuries and diseases. 

What a good return-to-work plan includes

Element	Why it helps
Agreed hours and duties	Prevents overload in the first weeks
Clear points of contact	Reduces confusion and repeated retelling
Review dates	Lets the plan change as recovery changes
Privacy settings	Protects dignity and trust
Manager briefing	Makes support more consistent
Work adjustments	Helps the person succeed, not just return

Examples of adjustments include a temporary drop in workload, fewer emotionally heavy tasks, flexible start times, or quieter workspaces.

Strategy 9: Focus on prevention, not only perks

Perks are fine. Fruit bowls, mindfulness sessions and wellbeing days can all play a useful part. Still, they are not the core fix. Prevention means changing the work itself.

Prevention versus surface action

Surface action	Better prevention move
Resilience webinar	Review workload, control and staffing
Free meditation app	Fix bullying reports and poor behaviour
One wellbeing day	Build daily manager check-ins
Poster campaign	Improve role clarity and change communication
Pizza after overtime	Reduce the overtime

This is where many workplaces get stuck. They invest in support after harm appears, rather than remove the causes that keep creating harm.

A practical 90-day action plan for employers

Days 1 to 30

• Review leave, turnover and complaint data 
• Ask teams where work pressure is highest 
• Check whether managers know the psychosocial risk process 
• Map current support options 
• Identify one high-risk team for deeper action 

Days 31 to 60

• Run manager training on mental health conversations 
• Fix one clear workload issue 
• Review role clarity in high-pressure teams 
• Refresh bullying and reporting pathways 
• Brief leaders on change communication standards 

Days 61 to 90

• Measure early results 
• Ask staff what has improved and what has not 
• Update risk controls 
• Build regular mental health reporting into leadership meetings 
• Set a yearly review cycle 

What success looks like

A mentally healthy workplace does not mean stress disappears. Work will still have deadlines, pressure and hard days. Success means the pressure is manageable, support is real and recovery is possible.

Signs you are moving in the right direction

• Staff raise concerns earlier 
• Managers deal with issues sooner 
• Workloads become more visible and fair 
• Sick leave stabilises 
• Turnover drops 
• Trust improves in surveys 
• People return from leave with better support 
• Teams stop seeing stress as a personal failure 

That shift matters. It takes a workplace from reaction to prevention and from silence to action.

Why this matters for Australian businesses right now

Australian employers are working in a setting where mental health, safety and legal duties are becoming harder to separate. Safe Work Australia has made psychosocial hazards a clear part of work health and safety practice and Comcare’s current guidance points to a code that identifies 17 psychosocial hazards. 

So this is no longer just an HR issue. It is a leadership issue, a safety issue and a performance issue.

If your business wants fewer absences, better retention and stronger teams, start with the work itself. Ask what is causing strain. Ask who is carrying too much. Ask where silence has become normal. Then act on the answer.

Conclusion

Managing mental health in the workplace requires consistent action, not one-off initiatives. When organisations focus on clear job design, supportive leadership, fair workloads and early intervention, they create an environment where people can perform without being overwhelmed. Over time, this approach leads to stronger teams, lower absenteeism and a workplace where employees feel capable, supported and ready to contribute.

FAQs

1. What is mental health in the workplace?

Mental health in the workplace refers to how work conditions, relationships and organisational practices affect an employee’s psychological wellbeing. It includes factors such as workload, job control, support from managers, workplace culture and access to resources. When workplaces actively manage these elements, employees are more likely to feel safe, valued and capable of performing their roles without experiencing harmful levels of stress.

2. What causes stress-related absenteeism at work?

Stress-related absenteeism usually develops over time due to ongoing workplace pressures rather than a single event. Common causes include excessive workload, lack of support, unclear expectations, poor management practices and exposure to conflict or trauma. When these issues remain unaddressed, they can lead to burnout, anxiety, or other mental health challenges, ultimately causing employees to take time off to recover.

3. Are Australian employers required to manage psychosocial hazards?

Yes, Australian employers have a legal duty under work health and safety laws to manage psychosocial hazards just as they would physical risks. This includes identifying hazards such as high job demands, bullying, or poor organisational change processes, assessing the level of risk and implementing controls to reduce harm. Employers must also review and improve these controls regularly to ensure the workplace remains safe.

4. How can managers support mental health without acting like therapists?

Managers play a critical role in shaping a mentally healthy workplace, but they are not expected to provide clinical support. Instead, their role is to create clear expectations, manage workloads effectively, communicate openly and respond early to signs of distress. By listening without judgment, offering practical adjustments and guiding employees toward appropriate support services, managers can make a significant difference without stepping outside their professional boundaries.

5. What is the best way to reduce stress-related absenteeism?

The most effective way to reduce stress-related absenteeism is to focus on prevention by improving how work is designed and managed. This includes setting realistic workloads, ensuring clear communication, providing strong leadership support and addressing workplace behaviours that contribute to stress. While wellbeing programs can help, they are most effective when combined with structural changes that remove or reduce the root causes of workplace pressure.
