Economic Impact Studies
For every pound spent on employee health and safety, manufacturing employers get back an average of £1.24 (24% ROI), construction employers get back £1.34 (34% ROI), and transportation employers get back £2.14 (114% ROI) OSG.
Mental health interventions show an estimated return on investment of £4 for every pound invested PubMed Central.
A study of an Ontario textile plant showed that every £1 spent on ergonomics interventions provided a return of over £4 in health and productivity benefits OSG.
A meta-analysis of workplace health promotion programs found an overall weighted ROI of 1.38, indicating a 138% return on investment ResearchGate.
Small business health risk management programs showed ROI estimates of £0.58 to £1.00 for medical costs, £1.45 to £1.00 for productivity-related expenditures, and £2.03 to £1.00 when medical and productivity savings were combined PubMed Central.
Specific Intervention Outcomes
Occupational health management programs focusing on self-efficacy reduced sickness absence rates from 9.26% to 7.93% in the intervention group, while control groups saw increases from 7.9% to 10.7% PubMed.
For high-risk employees, occupational health interventions reduced mean sickness absence from 30 days in the usual care group to 19 days in the intervention group, a difference of 11 days PubMed.
Economic Cost of Sickness Absence
Dame Carol Black’s 2008 review found that sickness absence costs the UK economy £103 billion annually, with the total cost of working-age ill-health to the economy estimated at over £100 billion per year Working for a Healthier Tomorrow: Dame Carol Black’s Review of the Health of Britain’s Working Age Population +2.
Employers pay £9 billion annually on sick pay and associated costs, while the state spends £13 billion on health-related benefits, and £15 billion in economic output is lost from sickness absence each year GOV.UK.
The average cost of a lost-time injury ranges from £90,000 to £180,000 depending on the industry sector, including £30,000-£60,000 in direct costs OSG.

Important Caveats
While many studies report positive ROI, the quality of such studies is generally variable, with common flaws in study design, lack of sound assumptions, and poor application of economic evaluation methods Personnel Today. When accounting for methodological quality, higher quality studies tend to show smaller financial returns than lower quality studies ResearchGate.
The evidence suggests occupational health absence management programs can deliver positive ROI, particularly when interventions are well-designed, targeted at appropriate populations, and include both medical and productivity-related cost savings.
