The ROI of Employee Wellbeing: Making the Business Case
When budgets are tight, “wellbeing” can quickly get parked in the nice-to-have pile. Yet in many South West SMEs, the real cost is already showing up elsewhere: higher absence, more mistakes, slower service, and managers spending evenings firefighting people issues instead of running the business. The business case for wellbeing is not about perks. It’s about performance, risk, and creating the conditions where people can do great work, consistently.
Start with the truth: wellbeing is already on your balance sheet
You may not have a line in your accounts labelled “wellbeing”, but you almost certainly have costs linked to:
- Sickness absence and long-term health issues
- Staff turnover and recruitment spend
- Reduced productivity when people are present but running on empty
- Customer complaints, quality issues and rework
- Accidents, near misses, and stress-related grievances
A practical way to frame this with senior leaders is: we are paying for wellbeing either way, we just get to choose whether we pay reactively or invest proactively.
The legal and risk angle: this is not optional
Part of the ROI is risk reduction. UK employers have clear duties to protect employees’ health, safety and welfare. Poorly managed stress, excessive hours, bullying cultures, and a lack of support can become legal exposure, as well as reputational damage in a small local labour market.
A strong wellbeing approach supports safer work, better management behaviours, and more consistent decision-making, including around absence management, flexible working, and reasonable adjustments.
What “good” looks like in a small business (without turning into a corporate programme)
For most SMEs across Devon and Cornwall, the best wellbeing strategy is simple and embedded:
1) Capable line managers
Your managers shape day-to-day experience more than any policy. Investing in manager confidence around workload planning, supportive conversations, early intervention and fair boundaries often delivers the quickest return.
2) Work design, not just wellness activities
Fruit bowls and mindfulness apps do not fix unrealistic workloads, unclear priorities, or constant last-minute changes. The highest impact actions usually sit in: capacity planning, role clarity, job design, and decision-making rhythms.
3) A culture where people can speak up early
When people feel listened to, issues surface sooner and are easier to resolve. This is where trust pays dividends: fewer surprises, fewer resignations, fewer “it’s got too much” moments.
Turning “wellbeing” into a financial case: a simple ROI framework
You do not need perfect data. You need a clear baseline and a credible method.
Step 1: Define the business problem in plain terms
Example: “Absence has increased, overtime is creeping up, errors are rising, and supervisors are spending too much time managing short-notice cover.”
Step 2: Pick 3–5 measurable indicators
Choose what matters most to your operation, such as:
- Absence rate and duration (especially stress, MSK, anxiety/depression where disclosed)
- Staff turnover in key roles
- Overtime and temporary labour spend
- Time-to-competence for new starters
- Customer complaints, rework, near misses
Step 3: Agree the intervention and cost it properly
Include: training time, external support, tools, comms, and manager time.
Step 4: Estimate conservative benefits
Use cautious assumptions. For example:
- A modest reduction in absence days
- A small decrease in leavers in hard-to-fill roles
- Fewer quality errors or call-backs
- Less overtime needed to cover gaps
Step 5: Calculate and report simply
A basic approach:
- ROI (%) = (Estimated annual savings – annual programme cost) ÷ annual programme cost x 100
- Add a short narrative on risk reduction and operational stability (often what leaders value most).
A South West example: how ROI shows up in real workplaces
Hospitality business in Cornwall
Peak season pressure leads to long shifts, frayed tempers, and higher turnover just when you need stability. A wellbeing plan focused on rotas, breaks, manager behaviour, and early check-ins can reduce last-minute absence and improve retention through the season. The return shows up as fewer agency shifts, better guest experience, and less time spent recruiting mid-summer.
Engineering or manufacturing in Plymouth
When fatigue creeps in, mistakes and near misses rise. Small adjustments to shift patterns, workload planning, and supervisor training can protect quality and safety. The return shows up in fewer reworks, reduced incident risk, and steadier output.
Care provider in Devon
Emotional load is high, and absence can snowball quickly. A practical support structure for managers, better return-to-work conversations, and clearer escalation routes can reduce long-term absence and protect continuity of care. The return shows up in lower sickness disruption, stronger morale, and better service resilience.
Practical takeaways: what to do in the next 30 days
- Run a short “what’s getting in the way” listening exercise: keep it focused on workload, clarity, support, and barriers to doing a good job.
- Review your top 3 pressure points: rotas, workload, role clarity, customer demand spikes, change management.
- Train managers on early conversations: how to spot changes, ask the right questions, agree support, and document fairly.
- Make adjustments easier: a simple process for flexible changes, phased returns, and reasonable adjustments, so managers do not avoid action through uncertainty.
- Pick measures you will actually track: one operational measure, one people measure, one risk measure, reviewed monthly.

The bottom line
The strongest wellbeing business cases do not try to “sell kindness”. They show how better-managed work reduces disruption, strengthens performance, and lowers people risk. When your workplace helps people stay well, you get more consistency, better decisions, and a culture where problems are solved earlier, not later.
