Let us start with a number. Replace a single mid-level employee in Nairobi and it costs your company between six and nine months of that person's salary. That includes advertising the role, interviewing candidates, the recruitment agency fee, onboarding, training, and — most importantly — the productivity loss while the new person gets up to speed. For a role paying KES 150,000 per month, you are looking at roughly KES 900,000 to KES 1.35 million per departure. If you lose ten people a year, you have lost more than most companies spend on their entire marketing budget.
Now ask yourself: why did those ten people leave? In most exit interviews, people say "better opportunity" or "career growth." They are being polite. What they usually mean is: "I was exhausted, undervalued, poorly managed, and nobody seemed to care." The real reasons people leave are almost always wellness-related — burnout, toxic management, lack of flexibility, feeling invisible. But because these problems are hard to measure, they get ignored in favour of things that are easy to measure, like revenue and headcount.
What "Wellness ROI" Actually Means
When business leaders hear "workplace wellness," they often think of yoga classes, fruit baskets, and mental health days. These are nice. They are also almost completely useless as strategies. They are band-aids on a wound that requires surgery. The real return on investment from wellness is not about making people feel slightly less miserable. It is about removing the structural conditions that make them miserable in the first place — and measuring the business impact of doing so.
The companies that take wellness seriously see reductions in sick leave (people who are not chronically stressed get sick less often), lower turnover (people who feel valued stay longer), higher productivity (people who are not running on cortisol and caffeine think more clearly), and better customer service (people who are not miserable are nicer to clients). These are not "soft" outcomes. They are financial outcomes that show up on your profit and loss statement — you just have to be willing to track them.
The Hard Conversation
Most organisations are reluctant to invest in wellness because the costs are immediate and the returns are delayed. Building a healthier workplace takes months. The payoff appears in reduced turnover, fewer sick days, and better performance — none of which show up in next quarter's report. So the leadership team says "we will get to it" and then never does, because there is always something more urgent.
But here is the uncomfortable truth: you are already paying for wellness. You are paying for it through the cost of replacing burned-out employees, through the productivity loss of people who are physically present but mentally checked out, through the reputation damage when your company becomes known as a place that chews people up. You are paying. You are just paying at the wrong end — after the damage is done instead of before it starts.
