Employee Health and Wellbeing as ESG Metrics
How Does Employee Health and Wellbeing Factor Into ESG?
Workforce health is simultaneously a humanitarian concern and a financial driver. The estimated cost of mental health conditions alone in the US economy exceeds $1 trillion annually (Deloitte), primarily through presenteeism, absenteeism, and disability costs. Companies that invest effectively in employee health and wellbeing — physical, mental, and financial — achieve measurable reductions in these costs alongside improvements in productivity, retention, and employer brand. For ESG investors, health and wellbeing programs represent a dimension of human capital management that affects long-run competitive position.
Employee health and wellbeing metrics measure the quality and effectiveness of a company's programs for protecting and promoting the physical, mental, and financial health of its workforce — and the business outcomes associated with those programs.
Key Takeaways
- Occupational health and safety (OHS) metrics (TRIR, LTIR, fatality rate) are the foundation of health measurement; see also the labor practices metrics article.
- Mental health investment has become a distinct ESG metric as awareness of mental health costs has grown; few companies disclose quantitative mental health metrics but trend is improving.
- Employee Assistance Programs (EAPs), mental health days, and access to psychological support are increasingly assessed by ESG analysts.
- Financial wellbeing programs — retirement adequacy, financial counseling, emergency savings programs — reduce financial stress and associated productivity loss.
- CSRD ESRS S1 creates EU mandatory disclosure on health and safety and work-life balance provisions from 2025.
Occupational Health and Safety: The Core Metrics
Physical health in the workplace is measured primarily through injury and illness statistics, which are covered in depth in the Labor Practices Metrics article. The additional dimension relevant to wellbeing analysis is the quality and coverage of occupational health management systems:
ISO 45001 certification: The ISO 45001 standard for occupational health and safety management systems provides a framework for continual improvement in workplace safety. Companies certified to ISO 45001 have demonstrated third-party validated management system quality. Certification rate among production employees and contractor workers signals safety management comprehensiveness.
Occupational health surveillance programs: Regular health monitoring for employees exposed to specific workplace hazards — hearing tests in noisy environments, lung function testing in dusty workplaces, musculoskeletal screening for repetitive-motion roles — demonstrates proactive health management.
Return to work programs: The quality of rehabilitation and return-to-work programs for injured employees affects both worker outcomes and workers' compensation costs. Companies with structured, goal-oriented rehabilitation programs return injured workers to productivity more effectively and incur lower long-term disability costs.
Mental Health: The Emerging Dimension
The Scale of the Problem
Mental health conditions affect approximately 1 in 4 adults in developed economies at some point annually. Depression and anxiety are the leading causes of disability-adjusted life years among working-age adults globally. Occupational stress — driven by workload, lack of control, poor relationships, job insecurity, and organizational change — is a primary driver of both mental health conditions and voluntary turnover.
The COVID-19 pandemic accelerated mental health awareness and significantly increased reported burnout, particularly in healthcare, education, and knowledge-economy sectors with boundary-blurred remote work. The American Psychological Association's Work and Well-Being Survey found that 77% of US workers reported work-related stress in 2023.
Disclosure Landscape
Mental health metrics are among the least standardized in ESG disclosure. Companies typically disclose:
- Whether an Employee Assistance Program (EAP) is available (most large employers)
- EAP utilization rates (occasionally; raises privacy questions)
- Mental health training for managers (increasingly disclosed)
- Whether the company is a signatory to the Mind Workplace Wellbeing Index or Mindful Employer Charter (UK)
- Whether mental health first aiders are trained and deployed
Quantitative mental health outcome metrics — incidence rates of stress-related absence, mental health claim rates, burnout survey scores — are rarely disclosed publicly due to privacy concerns and stigma. Third-party wellbeing platforms (Unmind, Calm for Business, Headspace for Work) sometimes provide anonymized population-level utilization data to employers that can be shared in aggregate.
Investor Materiality
For companies in talent-intensive industries where burnout risk is high — investment banking, law, consulting, technology, healthcare — mental health culture is a genuine competitive differentiator. Goldman Sachs's 2021 leaked survey showing first-year analysts working 95 hours per week and reporting severe health impacts caused significant reputational damage and triggered policy changes across the investment banking industry.
Financial Wellbeing
Financial stress is associated with reduced productivity, absenteeism, and mental health deterioration — creating a spillover from employees' personal financial situations into employer productivity outcomes. Financial wellbeing programs include:
Retirement adequacy: The quality of retirement benefit programs affects long-term employee financial security. For US companies, defined contribution plan participation rates, employer match rates, and investment menu quality are quantifiable metrics. The shift from defined benefit to defined contribution plans has shifted retirement risk to employees — ESG assessment should consider whether employees are genuinely accumulating adequate retirement savings.
Financial counseling and coaching: Employer-sponsored financial education and coaching programs reduce financial stress and improve retirement savings behavior. Several large employers including Walmart, Home Depot, and Bank of America have implemented financial coaching programs with demonstrated outcomes.
Emergency savings programs: Emergency savings deficits are associated with financial fragility among lower-income employees. Programs enabling small emergency savings through payroll deduction — pioneered through the Aspen Institute's Financial Security Program — help employees avoid payday lending and financial crisis spirals.
Living wage and wage growth: Foundational to financial wellbeing, covered in the Labor Practices Metrics and Pay Equity articles.
Work-Life Balance and Flexible Working
Post-pandemic normalization of hybrid and flexible working arrangements has made work-life balance a more visible employer differentiator. Metrics include:
- Percentage of roles eligible for hybrid or remote work
- Parental leave generosity (weeks of paid leave for all parents, not just birth mothers)
- Vacation day accrual and utilization rates
- Right to disconnect policies
- Average weekly working hours (where disclosed)
ESRS S1 specifically requires disclosure on work-life balance provisions, including parental leave take-up rates by gender — a metric that reveals whether male employees actually use available parental leave (low male take-up perpetuates gender career gaps).
The Business Case
Rigorous investment in employee health and wellbeing programs produces measurable financial returns:
- Deloitte research (2020) found an average return of £5.30 for every £1 invested in employee mental health programs in the UK, driven by reduced absenteeism, presenteeism, and turnover.
- Johnson & Johnson reported that its comprehensive employee health program produced savings of $250 million over a decade through reduced healthcare costs and productivity improvements.
- Harvard Business School research found that companies in the top quintile for employee satisfaction generated significantly higher five-year total shareholder returns than those in the bottom quintile.
These findings do not establish universal causality — companies with strong financial positions can afford better health programs — but the correlation is consistent enough to justify inclusion in fundamental investment analysis.
Common Mistakes
Conflating health and safety with broader wellbeing. TRIR and LTIR measure physical injury rates; they do not capture mental health, financial stress, or work-life balance quality. A company with excellent TRIR and a toxic culture that drives burnout and depression has a selective picture of employee wellbeing.
Treating EAP availability as a wellbeing quality metric. Over 90% of large employers in the US and UK offer EAPs; availability is nearly universal. Utilization rates, program breadth, and integration into a comprehensive wellbeing strategy are more differentiating metrics.
Ignoring the quality of part-time and contract worker benefits. Many companies offer excellent health and wellbeing programs to permanent full-time employees while providing minimal benefits to part-time, temporary, or gig workers. For companies with high non-permanent workforce proportions, this creates a two-tier system with significant wellbeing risk concentrated in the more vulnerable population.
Frequently Asked Questions
Is mental health disclosure improving? Yes, gradually. Investor pressure through frameworks including the Workforce Disclosure Initiative (WDI) and institutional investor engagement on employee wellbeing is driving more detailed disclosure. Some leading companies now publish employee Net Promoter Scores (eNPS), engagement scores, and burnout survey results. ESRS S1's requirement for disclosure on health and safety measures (including "psychological health and safety") will standardize and mandate more disclosure from EU companies from 2025.
How do health and wellbeing metrics relate to turnover? High-quality health and wellbeing programs are associated with lower voluntary turnover, particularly for programs targeting mental health, financial stress, and work-life balance. The causal direction is plausible: reducing employee stress and increasing wellbeing improves job satisfaction, which reduces turnover intent. Companies can verify this linkage internally through engagement survey correlations.

Summary
Employee health and wellbeing is a multidimensional ESG social metric spanning physical safety (OHS), mental health, financial wellbeing, and work-life balance. Physical safety metrics are the most standardized; mental health remains the least disclosed but fastest-growing dimension of investor interest. The business case — measurable productivity, retention, and healthcare cost outcomes — grounds health and wellbeing investment in financial materiality rather than ethical aspiration alone. CSRD ESRS S1 will significantly improve EU disclosure comparability from 2025. For investors, the most analytically useful metrics combine TRIR/LTIR with parental leave take-up, EAP utilization, engagement scores, and voluntary turnover trends to build a comprehensive picture of workforce health management quality.
