When we think about volunteering, we often imagine people helping at food banks, mentoring young people, or planting trees in their local park. What may not spring to mind immediately is how volunteering connects back to the workplace. Yet, more and more companies are investing in corporate volunteering programs (e.g. opportunities for employees to volunteer through employer-sponsored initiatives).
But does this kind of volunteering make a difference at work? Does giving time to help others translate into feeling happier or performing better on the job? Our new Systematic review of research suggests that it just might, though the relationship is more complex than it first appears.
Why study volunteering at work?
Volunteering is already well recognised for its personal benefits. Studies show it can boost mental health, reduce stress, and foster a sense of purpose and connection. But while the link between volunteering and personal wellbeing has been studied extensively, its impact on work outcomes, like job satisfaction (how happy people are at work) and job performance (how well they do their tasks) hasn’t been explored thoroughly.
Given that many organisations now encourage employees to volunteer as part of their corporate social responsibility (CSR) strategies, understanding these workplace effects matters. If volunteering helps employees feel more engaged, more satisfied, and even more productive, it’s not just good for society, it’s good for business.
What did we do in our study?
To find answers, researchers looked across six major academic databases to identify studies that examined the relationship between corporate volunteering and job-related outcomes among working adults.
In total, ten relevant studies were identified. Together, these studies provided a window into how volunteering interacts with job satisfaction and performance, and what factors might shape those effects.
What did our study find?
- Job satisfaction: 86% of the studies reported a positive relationship between volunteering and job satisfaction. In other words, employees who volunteered tended to feel happier in their jobs.
- Job performance: The evidence here was more mixed with 57% of studies reporting a positive association. Importantly, performance benefits didn’t increase endlessly with more volunteering. Instead, an S-shaped pattern emerged. Moderate levels of volunteering seemed to boost performance, but too little or too much had weaker or negative effects.
Other key factors also influenced the outcomes:
- CSR attitudes: If employees believed volunteering was motivated mainly by team-building or company image, the positive effects were weaker. Authentic, driven by community-needs volunteering mattered more.
- Skill alignment: When volunteering tapped into employees’ professional skills, it was more likely to improve both satisfaction and performance.
- Intensity of participation: Frequency and depth of involvement shaped the outcomes, too much could create strain, while the right balance fostered growth.
Why might volunteering help at work?
Several psychological theories help explain these findings.
- Social Exchange Theory suggests that when employees feel supported by their employer (for instance, by being given time to volunteer), they respond with greater commitment and satisfaction.
- Organisational Support Theory suggests that when employees feel their volunteering efforts are genuinely valued by their company, they may experience a greater sense of value and belonging.
- Job Demands-Resources (JD-R) model offers another angle: volunteering can act either as a resource or a demand, depending on its intensity and the organizational context. As a resource, volunteering can provide skills, social connections, and personal growth that help balance job demands, boost engagement and performance. However, if volunteering becomes too demanding, it may add strain instead o support.
So, as the S-shaped curve shows, balance is essential. Too much volunteering may pull employees away from core responsibilities or create stress, tipping it from a resource into a demand.
What does this mean for organisations?
The review offers several practical lessons for companies and HR professionals:
- Design meaningful programs. Volunteering works best when employees see it as genuine and socially valuable, not just a corporate PR exercise. Communicating purpose clearly is crucial.
- Align volunteering with skills. Giving employees opportunities to use and develop their professional skills through volunteering not only benefits the community but also enhances satisfaction and workplace performance.
- Mind the balance. Moderate levels of involvement appear optimal. Too little won’t generate benefits, while too much could backfire. Companies should help employees find the sweet spot.
- Foster social connection. Volunteering often builds bonds between employees, which in turn strengthens morale and teamwork back at work. Encouraging group volunteering opportunities can amplify this effect.
What next?
This systematic review is the first to focus specifically on volunteering’s impact on job satisfaction and job performance. While the evidence points to clear benefits, it also highlights complexity. Future research will need to:
- Test these relationships in more diverse contexts (most existing studies come from high-income countries).
- Explore new forms of volunteering, such as remote volunteering in our increasingly hybrid and digital workplaces.
- Use longitudinal designs (tracking people over time) to untangle cause and effect more clearly.
Volunteering is often seen as something we give outward, a way to help others. But as this review shows, it also gives back, to employees and the organisations they work for. When done well, corporate volunteering creates a virtuous circle: employees feel more satisfied, performance can improve, and communities benefit too.
The challenge for companies is to harness these benefits thoughtfully. Volunteering should not feel forced, superficial, or overwhelming. Instead, it should be authentic, purposeful, and balanced. Get that right, and volunteering becomes more than a feel-good initiative, it becomes a powerful tool for employee wellbeing and organisational success.
So, the takeaway is clear: thoughtfully designed corporate volunteering programs can do more than just serve communities, they can also enrich employees’ work lives.
