Every people leader is under pressure to keep good staff without endlessly raising pay. The 2026 evidence points to a lever most companies already own and badly under-use: volunteering.
Not as a nice-to-have. As one of the most cost-effective retention interventions available to a modern employer.
The number that should stop you
In a randomised field experiment published in Management Science in 2024, a single day of volunteering cut employee turnover by half over the following year. Randomised, not correlational, which means the volunteering did the work.
It is not a one-off finding. Benevity's research shows 52% lower turnover among newer employees who take part in purpose programmes. And 87% of employees say workplace volunteering factors into whether they stay or leave (Deloitte, 2024). When you cost out a single avoidable resignation, the maths on a well-run volunteering programme becomes very easy.
It is not just retention. It is wellbeing.
Here is a finding that sets volunteering apart from the usual run of wellness perks. Of all the workplace interventions studied by the Oxford Wellbeing Research Centre in 2024, volunteering was the only one that consistently improved employee wellbeing at a collective level.
Fruit baskets and meditation apps come and go. The evidence says giving people a meaningful way to help others does something the others do not.
The talent point you cannot ignore
If you recruit anyone under 40, purpose is not soft. It is a hiring and retention condition.
In Deloitte's 2025 survey of more than 23,000 people, 40% of Gen Z and 51% of millennials said they have left a job because it lacked purpose. Around a third have rejected an employer outright over its values. Your youngest and most mobile talent is the most likely to walk if the work feels hollow.
A visible, easy-to-join volunteering programme is one of the clearest signals you can send that this is a place where people can do good, not just do a job.
Why your current programme probably underperforms
Most companies have a volunteering policy. Very few have real participation. Even after record growth, corporate volunteering participation reached only 13.6% in 2025 (Benevity). Around 86 in every 100 employees still take no part.
The reasons are consistent, and none of them is apathy:
- People do not know it exists, or are not sure they are allowed to use work time.
- It is too rigid. A single flagship "volunteering day" excludes anyone who is busy that day. Micro-volunteering, small and flexible actions, is now around 60% of all corporate volunteers. Flexibility is how most people actually take part.
- It is too much effort to find something suitable. If an employee has to hunt for an opportunity that fits their skills and schedule, most will not.
When companies offer more and more flexible ways to take part, participation rises around twelvefold on average (Benevity). Breadth and ease, not exhortation, is what moves the number.
What good looks like for people teams
- Offer a range of options: local, virtual, skills-based, micro-actions, team days.
- Make the time allowance explicit and easy to book, so nobody wonders whether they are allowed.
- Match people to opportunities that fit their skills and interests, rather than making them search.
- Capture the hours and tell the story back, both to the individual and to leadership.
Do that, and volunteering stops being a line in the handbook and becomes one of the strongest retention, engagement and wellbeing tools you have, at a fraction of the cost of the alternatives.
