The construction industry faces psychosocial risks that differ fundamentally from those in office-based environments. Project-based employment, transient workforces, physically demanding conditions, and deeply embedded cultural norms create a distinct risk profile that standard workplace mental health approaches fail to adequately address. This article examines the unique psychosocial hazards affecting construction workers and the control measures that have proven effective in managing them.

The Scale of the Problem

Construction workers experience psychological harm at rates that place the industry among the highest-risk sectors globally. In Australia, the age-standardised suicide rate for male construction workers between 2001 and 2019 was 26.6 per 100,000, approximately double the rate for other employed men at 13.2 per 100,000, according to research published in Scientific Reports (2022) by researchers at the University of Melbourne.

SafeWork NSW reports that construction workers are six times more likely to die from suicide than from a workplace accident. Young construction workers are more than twice as likely to take their own lives compared to other young Australian men of the same age. Across the construction, mining and energy sectors, approximately 190 workers die by suicide each year—an average of one every second day.

A 2022 SafeWork NSW survey found that 84% of construction industry respondents believe poor mental health is an issue in their sector. When asked to identify the top factors affecting worker wellbeing, workload, work pressures, time constraints, and excessive hours were cited as the leading contributors at 26% of responses.

Research by PricewaterhouseCoopers (2014) found that 25.1% of construction workers in Australia were affected by mental health conditions within a 12-month period, including affective disorders and substance use disorders—a rate substantially higher than many other industries.

Why Construction Is Different: Unique Industry Characteristics

Project-Based Employment and Job Insecurity

Unlike sectors with permanent employment structures, construction operates on a project-by-project basis. Workers move between employers, sites, and locations as projects commence and conclude. This creates chronic job insecurity that research consistently identifies as one of the strongest predictors of psychological harm.

A 2021 meta-analysis published in Safety Science analysed 48 studies involving 13,083 construction workers and found job insecurity had a correlation coefficient of 0.31 with mental health problems, making it one of the four most significant psychosocial hazards in the industry alongside role conflict (0.41), role ambiguity (0.35), and interpersonal conflict (0.31).

The temporary nature of construction projects makes it difficult to provide long-term support structures. Workers may lack continuity of supervision, established relationships with colleagues, and consistent access to support services as they transition between projects.

Physical Environment as a Root Cause

Research by Dr Carol Hon at Queensland University of Technology used Bayesian Network modelling to evaluate the interdependence of psychosocial hazards among Australian construction workers. The analysis revealed that poor physical environment, contract pressure, and lack of co-worker support were "root nodes" that influenced the probability of experiencing other psychosocial hazards.

This finding challenges conventional approaches that treat psychosocial hazards as independent items on a checklist. In construction, the physical working environment—exposure to weather extremes, noise, dust, hazardous materials, and physically demanding tasks—directly amplifies other psychosocial risks rather than existing separately from them.

Work Organisation and Time Pressure

Construction projects operate under fixed deadlines, liquidated damages clauses, and resource-constrained contracts. Workers must complete projects on time, to standard, and within budget—often simultaneously managing competing demands from multiple contractors and subcontractors.

A systematic review published in 2025 in the Sage Journals identified the key psychological harm factors in construction as job insecurity, long working hours, high demands, poor work-life balance, and workplace bullying. Studies consistently find construction workers reporting shifts exceeding 12 hours per day and workweeks extending to 47 hours or more.

The US Occupational Safety and Health Administration (OSHA) has documented that working 12-hour shifts is associated with a 37% increased risk of injury, while accident rates are 18% higher during evening shifts and 30% higher during night shifts compared to day shifts.

Masculine Culture and Help-Seeking Barriers

The construction industry culture is dominated by traditional masculine beliefs including self-reliance and stoicism, which act as barriers to help-seeking. Research has positively linked self-reliance beliefs to increased risk of suicidal thinking.

A peer-reviewed study in Frontiers in Psychiatry (2021) found that construction apprentices demonstrated reluctance to report poor treatment or seek help, with workplace bullying described as entrenched in worksite and industry culture. This creates a self-reinforcing dynamic where workers experiencing distress are least likely to access available support.

Hazards Unique to Construction Subgroups

FIFO and Remote Workers

Fly-in-fly-out (FIFO) and drive-in-drive-out (DIDO) work arrangements are common in construction projects in remote locations. Research by the Future of Work Institute at Curtin University, in collaboration with the Centre for Transformative Work Design and the Mental Health Commission of Western Australia, found that 33% of FIFO workers reported experiencing "high" or "very high" psychological distress, compared to 17% of non-FIFO employees and 10% of average Australians.

FIFO workers face distinct psychosocial hazards including:

• Isolation from family and social networks: Extended rosters (such as 4 weeks on, 1 week off) create lengthy separations that strain relationships and remove support systems during periods of stress.

• Communication barriers: Limited access to reliable internet or phone reception at remote sites compounds feelings of isolation.

• High-compression rosters: Research has found that higher psychological distress results from high-compression rosters and work-family conflict.

• Fatigue from travel: The transition between work and home, combined with long shifts, disrupts sleep patterns and reduces recovery time.

In April 2019, the Australian federal government released Australia's first FIFO code of practice—Mentally healthy workplaces for fly-in fly-out workers in the resources and construction sectors—specifically recognising FIFO workers and their partners as an "at-risk group" for mental ill health.

Apprentices and Young Workers

Young construction workers face elevated and distinct risks. Australian construction apprentices are approximately two and a half times more likely to die by suicide than other young men of the same age, according to MATES in Construction data.

A 2021 mixed-methods study published in Frontiers in Psychiatry found that approximately one-third of apprentices reported suicidal ideation, and 64% reported knowing someone who had attempted suicide in the previous year. Apprentices who experienced suicidal ideation were more likely to also report workplace bullying.

Research has identified that apprentices face:

• Routine workplace bullying: This has been linked to poor mental health and suicidality, increased substance use, job dissatisfaction, and apprenticeship non-completion.

• Power imbalances: The hierarchical structure of construction sites leaves apprentices with low positional and personal power compared to supervisors and qualified trade workers.

• Transitional stress: Difficulties integrating into industry culture while still developing technical competence creates vulnerability during a critical career period.

• Limited reporting mechanisms: Fear of career consequences and industry norms around toughness discourage reporting of bullying or psychological distress.

A 2025 study published in BMC Public Health assessing MATES in Construction's bullying intervention program found that training could produce statistically significant improvements in attitudes and knowledge around bullying, emphasising the importance of early intervention during apprenticeship.

Lower-Skilled Workers

Within the construction industry, suicide risk is not evenly distributed. Research consistently shows that lower-skilled workers such as labourers are at the highest risk of suicide compared to those in higher-skilled positions.

This differential is attributed to lower-skilled workers having less job control, greater exposure to job insecurity, higher rates of workplace bullying, and more frequent periods of unemployment or underemployment. They are also less likely to have access to formal support structures or the resources to access private mental health services.

The Regulatory Framework

WHS Regulations on Psychosocial Hazards

Changes to the Model Work Health and Safety (WHS) Regulations in Australian states and territories during 2022-2023 created explicit obligations for persons conducting a business or undertaking (PCBUs) to manage psychosocial hazards and their risks.

Safe Work Australia's Model Code of Practice: Managing psychosocial hazards at work, published in August 2022, provides practical guidance on compliance. Under the model WHS Regulations (Division 11, Part 3.2), PCBUs must:

1. Identify psychosocial hazards that could give rise to risks

2. Eliminate psychosocial risks so far as is reasonably practicable

3. If elimination is not reasonably practicable, minimise risks so far as is reasonably practicable

4. Review and revise control measures

The regulations define "psychosocial hazard" as hazards that may cause psychological or physical harm and arise from the design or management of work, the working environment, plant at a workplace, or workplace interactions or behaviours.

In NSW, the Work Health and Safety Regulation 2025 strengthened requirements by explicitly mandating use of the hierarchy of controls when elimination is not reasonably practicable.

Construction-Specific Codes and Guidance

Western Australia has developed a Code of Practice: Mentally Healthy Workplaces for fly-in fly-out workers in the resources and construction sectors, recognising that FIFO work arrangements require sector-specific guidance beyond general workplace mental health requirements.

Safe Work Australia's construction-specific guidance identifies common psychosocial hazards in construction as including:

• High job demands

• Low job control

• Poor support from supervisors, managers, or colleagues

• Low role clarity

• Poorly managed change

• Low recognition and reward

• Poor organisational justice

• Traumatic events or material

• Remote or isolated work

• Poor physical environment

• Violence and aggression

• Bullying

• Harassment including sexual harassment

• Conflict or poor workplace relationships and interactions

Control Measures: What Works

Industry-Wide Programs

MATES in Construction: Established in 2008, MATES in Construction operates the most extensively evaluated construction-specific suicide prevention program globally. Built on a worker-to-worker peer support model, the program has trained more than 300,000 workers, with over 22,000 volunteering as on-site "Connectors" who help keep someone safe in crisis and connect them with professional help, and approximately 3,000 trained in suicide intervention.

Research published in Scientific Reports (2022) found that from 2001 to 2019, the construction industry's suicide rate declined by an average of 3% per year—double the rate of decline seen in other male workers. While causation cannot be definitively attributed, researchers noted this decline occurred during the period when construction-specific interventions were expanded.

A more recent report (Volume 7, 2025) by the University of Melbourne, commissioned by MATES in Construction, confirmed that male construction workers continue to die by suicide at nearly twice the rate of other employed men (25.7 per 100,000 vs 14.3 per 100,000), but that in several states including Queensland, Victoria, and South Australia, rates are steadily declining and converging with the national average.

The Blueprint for Better Mental Health and Suicide Prevention: Launched in 2018 by MATES in Construction with support from Beyond Blue, CFMEU, Master Builders Australia, and other industry bodies, the Blueprint provides a nationally agreed framework based on five pillars:

1. Promote work's positive impact on mental health

2. Reduce harmful impacts of work

3. Provide mental health and suicide prevention literacy

4. Facilitate early intervention and treatment

5. Provide return-to-work and ongoing support

More than 15 construction companies have formally committed to the Blueprint, working with MATES to identify specific strengths and needs for health-promoting initiatives.

Organisational-Level Controls

The hierarchy of controls requires PCBUs to prioritise higher-order controls (eliminating or redesigning work) before relying on lower-order controls (training or individual coping strategies).

Job design modifications:

• Realistic scheduling that accounts for actual task duration rather than optimistic estimates

• Providing workers with meaningful input into how work is organised and sequenced

• Clear role definitions and reporting lines, particularly important on sites with multiple contractors

• Predictable rostering to allow workers to maintain relationships and outside commitments

Physical environment improvements:

• Adequate welfare facilities including toilet access, clean drinking water, and rest areas

• Protection from weather extremes

• Reduction of exposure to noise, dust, and other physical stressors that compound psychosocial risk

Supervision and support:

• Training supervisors to recognise signs of distress and have early supportive conversations

• Reducing case manager or supervisor turnover to maintain relationship continuity

• Establishing clear escalation pathways for workers experiencing difficulties

Fatigue management:

• Limiting consecutive shifts and total weekly hours

• Mandatory rest periods, especially in physically demanding or high-risk work

• Monitoring fatigue through both subjective and objective measures

Research published in Occupational and Environmental Medicine found that fatigue significantly affects construction workers' physical and cognitive function, with implications for both safety and psychological wellbeing. A study using wearable sensors found that workers' hazard recognition performance and safety risk assessment deteriorated significantly when physiological fatigue measures exceeded specific thresholds.

Addressing Bullying

A three-pronged intervention program delivered by MATES in Construction between July 2023 and February 2024 in Queensland and the Northern Territory targeted:

1. Apprentice Resilience Training: Building coping strategies and awareness among apprentices

2. Supervisor Training: Four-hour sessions ensuring supervisors understand legal responsibilities and effective supervision strategies regarding bullying and harassment

3. Toolbox Training: 15-minute sessions for all trade workers emphasising the difference between bullying and banter, with the key message "don't be a bystander"

Evaluation of this program found statistically significant improvements in attitudes and knowledge across all three training groups.

Peer Support Networks

The MATES model empowers workers to look out for each other through layered training:

• General Awareness Training: Basic mental health literacy delivered to all workers on site

• Connector Training: More intensive training for volunteers who maintain a network of support and can identify workers in distress

• ASIST (Applied Suicide Intervention Skills Training): Advanced training for selected workers in crisis intervention

Qualitative research published in SSM – Qualitative Research in Health found that the MATES "network of safety" model has transformed social norms on construction sites, with workers reporting that suicide prevention is now embedded in daily workplace culture, and help-seeking seen as a strength rather than weakness.

Challenges and Emerging Concerns

Young Worker Suicide Rates Rising

Despite overall improvements, the University of Melbourne's 2025 report revealed a troubling trend: suicide rates among younger construction workers (aged 15-24) have risen in recent years, running counter to the overall decline.

MATES Australia CEO Jorgen Gullestrup stated: "We are seeing strong progress overall, but the increase in suicides among our youngest workers is deeply concerning. It shows we must double down on prevention and support for apprentices and younger men entering the industry."

Fragmented Employment Structures

The prevalence of subcontracting, labour hire arrangements, and short-term engagements creates challenges for implementing consistent psychosocial risk management. Workers may receive inconsistent training, fall outside organisational support structures, or lack clarity about which PCBU holds responsibility for their psychological health.

Research has identified that labour hire workers experience stigma that increases inter-group differentiation and subsequent workplace bullying.

Measuring Effectiveness

While there is evidence of declining suicide rates coinciding with industry intervention programs, establishing causation remains methodologically challenging. The 2022 systematic review of MATES effectiveness noted that most evaluation studies to date have been limited in design, and called for more rigorous longitudinal research.

Practical Implementation Guidance

For PCBUs operating in construction, effective psychosocial risk management requires:

Assessment:

• Use validated tools such as the People at Work survey (available until October 2026) to identify psychosocial hazards

• Consult with workers and health and safety representatives, recognising that some workers may require different consultation approaches

• Observe the workplace, particularly during high-pressure periods such as project deadlines

Risk assessment considerations (per Safe Work Australia Code of Practice):

• Duration: How long is the worker exposed to the hazards?

• Frequency: How often is the worker exposed?

• Severity: How severe are the hazards and exposures?

• Interaction: How do multiple hazards combine to increase overall risk?

Control implementation:

• Prioritise elimination and substitution over administrative controls and PPE

• Implement changes at the organisational level before relying on individual-level interventions

• Ensure control measures are appropriate for the specific workforce, considering factors such as literacy, language, shift patterns, and site conditions

Review:

• Establish regular review cycles, not just following incidents

• Monitor leading indicators including worker feedback, turnover rates, and absenteeism

• Document the risk management process and decisions

Conclusion

The construction industry's psychosocial hazard profile is shaped by characteristics inherent to the sector: project-based employment, physical work environments, time pressures, transient workforces, and cultural norms that discourage help-seeking. Effective risk management requires approaches designed specifically for this context rather than generic workplace mental health programs.

The evidence base, while still developing, indicates that industry-wide programs targeting cultural change (such as MATES in Construction) combined with organisational-level job design modifications can reduce psychological harm. However, emerging data on rising suicide rates among young workers and the persistent gap between construction and other industries demonstrates that sustained, coordinated effort is required.

Under current WHS regulations, PCBUs have clear legal obligations to identify, assess, and control psychosocial hazards. For construction businesses, meeting these obligations requires understanding the unique risk profile of the industry and implementing control measures at the appropriate level of the hierarchy.
