Addressing Construction Worker Mental Health Through Lean: What New Research Reveals
The physical demands of construction work are well understood across our industry. The mental and emotional demands receive far less attention, yet the data increasingly shows that they warrant equal concern.
In recognition of Mental Health Awareness Month, the Lean Construction Institute is sharing findings from a recent study, Addressing Construction Worker Mental Health Using Lean Approaches, which quantifies the scope of the challenge and identifies management practices associated with measurable improvements in worker well-being.
The study is based on 282 survey responses collected from U.S. construction workers between August 2024 and March 2025, along with interviews with eight construction practitioners in varying management and leadership roles. Among its most important conclusions: the mental health crisis in construction is severe, widespread, and addressable. Many of the Lean practices already embedded in our shared body of knowledge are directly linked to better mental health outcomes for the workforce.
The Numbers We Can’t Ignore
Construction workers comprise 7.4% of the U.S. workforce but account for 17.9% of all suicides. In 2021, 56 out of every 100,000 male construction workers died by suicide, approximately four times the national average. By any measure, this is a safety crisis, one that deserves the same urgency the industry applies to fall protection and struck-by hazards.
The survey results reinforce this conclusion. More than one-third of respondents (36%) reported that their job is more stressful than they anticipated when they entered the field. Thirty percent expressed concern that job-related stress will eventually result in physical or mental illness. Fifty-six percent reported a loss of interest or pleasure in their usual activities within the past month, and 46% reported feelings of depression or hopelessness during the same period. These indicators are consistent with clinical markers of depression, and they are present across the workforce.
Identifying Those Most at Risk
The research identifies several populations experiencing disproportionate levels of stress and disconnection.
Supervisors and forepersons are among the most affected. Only 16% of workers with no direct reports expressed concern that stress would harm their health. Among those managing 11 to 20 workers, that figure rises to 41%. The individuals responsible for holding crews together are frequently closest to burnout, and the industry has historically underinvested in support systems designed with their needs in mind.
Non-union workers reported higher stress levels than their union counterparts, 42% compared to 32%, suggesting that the structure, protections, and peer networks characteristic of union environments provide a meaningful buffer.
Mid-career workers reported the lowest sense of belonging of any experience group, below both new hires and senior professionals. While it is tempting to assume that experienced practitioners at mid-career have established their footing, the data indicates otherwise.
Workers with long commutes also showed measurably worse mental health outcomes. Those commuting more than 30 minutes were roughly twice as likely to report severe job stress and significantly more likely to report symptoms of depression compared to workers commuting under 30 minutes. This finding points to scheduling, local hiring, and site logistics as underappreciated mental health levers.
Leadership Is Not a Soft Factor
One of the clearest findings in the report concerns leadership behavior. Among workers who strongly believe that management prioritizes safety, only 24% expressed concern that stress would harm their health. Among workers who believe leadership does not prioritize safety, that number rises to 71%. The way leaders show up on the jobsite has a measurable effect on how workers experience stress in their own bodies.
Psychological safety remains an area of concern. Approximately 75% of workers reported feeling valued by their team, and 76% indicated they can safely raise concerns. However, 59% do not feel safe taking risks or challenging established ideas. While many workers are comfortable identifying day-to-day issues, a substantial portion remain hesitant to push back on decisions or raise more difficult concerns. That gap is precisely where valuable ideas and early warnings are most often lost.
Where Lean Comes In
Perhaps the most actionable finding in the report is also the most encouraging: the Lean methods already familiar to practitioners across our community correlate strongly with improved mental health outcomes.
Workers who participated in regular team discussions reported feeling connected to their team 100% of the time, compared with 21% among workers without regular meetings. Among workers who reported the lowest stress levels, 100% said their team goals were clear. Among the most stressed workers, that figure dropped to just 60%, suggesting that goal ambiguity and high stress go hand in hand. On jobsites using visual planning tools such as whiteboards and task boards, 93% of workers reported feeling valued by their team, compared with 63% on jobsites without them.
Daily huddles, clear goal-setting, pull planning, visual management, and participatory decision-making are already established elements of the Lean playbook. This research demonstrates that these practices do more than improve handoffs and reduce waste; they help workers feel seen, informed, and respected. The findings provide a compelling case for deepening Lean implementation across the industry.
Action Items for the Industry
For project leaders, crew leaders, and organizational leaders, the research points to several concrete starting points.
1. Conduct a Meaningful Daily Huddle
Conduct daily huddles as structured conversations in which every trade has a voice, with team goals made explicit and posted where crews can reference them throughout the day. Visual planning works best when implemented collaboratively, in direct partnership with the crews responsible for executing the work.
2. Invest in the Well-being of Forepersons and Supervisors
Make a point of checking in with them directly and regularly, not just about project status, but about how they’re doing. Provide training in stress management and mental health first aid, and ensure they know that seeking help is not only appropriate but actively supported, with clear pathways to that help available within the organization.
3. Expand Psychological Safety
Model safety leadership from the top of the organization. Actively invite disagreement and acknowledge individuals who raise difficult questions even when the answers are uncomfortable. The data confirms that workers observe leadership behavior closely, and what they see shapes their daily experience.
4. Make Resources Visible
The Construction Industry Alliance for Suicide Prevention, the 988 Suicide and Crisis Lifeline, and employer and union assistance programs exist to support workers in need. These resources should be posted in jobsite trailers, referenced in toolbox talks, and integrated into everyday conversation. Normalizing the discussion is essential to create jobsite cultures where asking for help is treated with the same seriousness as any other safety concern.
5. Account for Commute in Workforce Planning
When possible, prioritize local hiring for projects with demanding timelines or safety-critical scopes. For workers traveling longer distances, consider staggered shift starts to reduce traffic-related fatigue, or near-site housing options for extended assignments.
The Bottom Line
Mental health in construction is a systemic challenge, but it’s not a hopeless one. The same Lean practices that make our projects more predictable and efficient also appear to make them more humane. This alignment represents a significant opportunity for the industry to act.
