Breaking Voluntary Work in Science Delivers Career Gains but Raises Equity Concerns, Study Finds

By Yogesh Bajaj

Scientists who contribute unpaid time to charitable and non-profit initiatives are reaping measurable career benefits—from higher grant success rates to expanded professional networks—while also helping to dismantle systemic barriers in academia, according to a new analysis published in Nature. However, the study also warns that the growing expectation of voluntary work risks exacerbating inequities, particularly for early-career researchers and those from underrepresented backgrounds.

The research, released on 13 July 2026, provides the first large-scale empirical evidence linking voluntary science-related activities to tangible career advantages. The findings arrive at a time when funding agencies and universities are increasingly prioritizing public engagement and knowledge translation as key metrics for research impact, raising questions about how to balance recognition for voluntary contributions with fair labor practices in academia.

What Happened

The Nature study, led by an international team of science policy researchers, analyzed survey data from over 12,000 scientists across 42 countries, spanning disciplines from biomedical research to environmental science. Participants were asked about their involvement in voluntary activities—defined as unpaid work for charities, non-profits, or community-based science initiatives—over the past five years. The study then cross-referenced these responses with career outcomes, including grant funding success, publication records, and professional network growth.

The results were striking:

– Grant funding success: Scientists who volunteered at least 50 hours annually in public engagement programs—such as science festivals, school outreach, or citizen science projects—were 22% more likely to secure competitive research grants than their non-volunteering peers. The effect was most pronounced in fields where public impact is a key evaluation criterion, such as environmental science and public health.
– Network expansion: Researchers involved in charity-led science education projects reported a 35% increase in co-authorship opportunities with collaborators outside their primary institution. Many attributed this to the interdisciplinary nature of voluntary work, which often brings together scientists, educators, and policymakers from diverse fields.
– Skill development: Volunteers who organized community science events or mentored early-career researchers demonstrated higher leadership and project management scores in peer evaluations. These skills, the study notes, are increasingly valued by hiring committees and funding agencies but are rarely taught in formal academic training.
– Visibility and recognition: Nearly 40% of volunteers reported that their unpaid work led to invitations to speak at conferences, join advisory boards, or contribute to policy discussions—opportunities that can significantly boost career trajectories.

The study also found that voluntary work played a particularly important role for scientists from underrepresented groups. Women, researchers from low- and middle-income countries (LMICs), and first-generation academics reported that voluntary roles provided critical access to networks and resources that were otherwise difficult to obtain through traditional academic channels. For example, a biologist from Kenya interviewed for the study described how volunteering with a local science education charity helped her connect with international collaborators, ultimately leading to a co-authored paper in Science.

Why It Matters

The findings come at a pivotal moment for science policy. Over the past decade, funding agencies and universities have increasingly emphasized public engagement, knowledge translation, and societal impact as key criteria for evaluating research. The European Research Council (ERC) and the U.S. National Science Foundation (NSF) both introduced pilot programs in 2025 that explicitly consider applicants’ contributions to community science initiatives when awarding grants. Similar policies have been adopted by the Wellcome Trust, the Canadian Institutes of Health Research (CIHR), and Australia’s National Health and Medical Research Council (NHMRC).

However, the Nature study highlights a tension at the heart of this shift: while voluntary work is being recognized as valuable, it remains unpaid and often unacknowledged in formal academic structures. This creates a paradox where scientists—particularly those from marginalized backgrounds—are incentivized to take on unpaid labor to advance their careers, even as they face growing pressure to publish, secure funding, and meet other traditional metrics of success.

Dr. Elena Vasquez, a co-author of the study and a science policy researcher at the University of São Paulo, told Nature that the findings underscore the need for systemic change. “Voluntary work is filling gaps that institutions have failed to address—whether it’s mentorship, public engagement, or interdisciplinary collaboration,” she said. “But we can’t keep relying on the goodwill of scientists, especially those who are already disadvantaged, to do this work for free.”

The study’s authors call on universities and funding bodies to formalize the recognition of voluntary contributions in hiring, promotion, and grant evaluation processes. They suggest several policy changes, including:
– Integrating volunteer experience into tenure and promotion criteria, particularly for roles that demonstrate leadership, public engagement, or mentorship.
– Providing institutional support for voluntary initiatives, such as funding for community science projects or protected time for public engagement activities.
– Addressing inequities by ensuring that voluntary work does not become a de facto requirement for career advancement, particularly for early-career researchers and those from underrepresented groups.

Background and Context

The debate over voluntary work in science is not new, but it has gained urgency in recent years as funding agencies and universities place greater emphasis on broader impacts—a term used to describe the societal benefits of research. The U.S. National Science Foundation, for example, has required grant applicants to include a “Broader Impacts” section since 1997, but the criteria have become more stringent in the past decade. Similarly, the UK’s Research Excellence Framework (REF) now evaluates the “impact” of research beyond academia, including its contributions to public policy, education, and community engagement.

This shift reflects a growing recognition that science does not exist in a vacuum. Policymakers, funders, and the public increasingly expect researchers to demonstrate the real-world relevance of their work, whether through public outreach, policy engagement, or community-based research. However, these expectations have collided with the realities of academic life, where time is a scarce resource and traditional metrics—such as publication counts and grant funding—still dominate career advancement.

For many scientists, voluntary work has become a way to bridge this gap. A 2024 survey by the Royal Society found that 68% of UK-based researchers had engaged in some form of unpaid science communication or public engagement in the past year, with many citing career benefits as a key motivator. However, the same survey also revealed disparities in who is expected to do this work. Women, for example, were 30% more likely than men to report feeling pressured to take on unpaid public engagement roles, often at the expense of their research time.

The Nature study builds on this earlier research by providing quantitative evidence of the career benefits of voluntary work. However, it also raises ethical questions about the exploitation of unpaid labor in academia. Critics argue that the growing expectation of voluntary work is part of a broader trend of academic precarity, where early-career researchers—particularly those on fixed-term contracts—are expected to take on unpaid roles to remain competitive.

Competing Claims and Uncertainty

While the Nature study provides compelling evidence of the career benefits of voluntary work, it also acknowledges several limitations and areas of uncertainty:

1. Causation vs. correlation: The study shows a correlation between voluntary work and career success, but it does not prove causation. It is possible that scientists who are already well-connected or high-performing are more likely to engage in voluntary work, rather than the other way around. The authors note that randomized controlled trials would be needed to establish a causal link, but such studies are difficult to conduct in real-world academic settings.

2. Selection bias: The study relied on self-reported data from scientists who chose to participate in the survey. It is possible that those who had positive experiences with voluntary work were more likely to respond, while those who found it burdensome or unrewarding were underrepresented. The authors attempted to mitigate this by using a large, diverse sample, but they acknowledge that selection bias remains a concern.

3. Field-specific differences: The benefits of voluntary work may vary significantly across disciplines. For example, public engagement is often more highly valued in environmental science and public health than in theoretical physics or mathematics. The study did not break down results by field, leaving open the question of whether the findings apply equally across all areas of science.

4. Equity concerns: While the study highlights the benefits of voluntary work for underrepresented groups, it also warns that unpaid labor can exacerbate inequities. Scientists from LMICs, for example, may have fewer resources to devote to unpaid work, putting them at a disadvantage in grant competitions that prioritize public engagement. Similarly, early-career researchers—who are often on fixed-term contracts—may struggle to balance voluntary work with the demands of publishing and securing funding.

5. Institutional recognition: The study calls for universities and funding bodies to recognize voluntary work in hiring and promotion decisions, but it does not address how this might be implemented in practice. For example, how should institutions quantify the value of a scientist’s contributions to a community science festival or mentorship program? And how can they ensure that such recognition does not become another bureaucratic hurdle for researchers?

What to Watch Next

The Nature study is likely to fuel ongoing debates about the role of voluntary work in science, particularly as funding agencies and universities continue to prioritize public engagement. Here are the key developments to watch in the coming months:

1. Policy changes at funding agencies: The ERC and NSF have already signaled that they are reviewing their grant evaluation criteria to place greater emphasis on public engagement. The Nature study could accelerate this trend, leading to new guidelines for how voluntary work is assessed in grant applications. However, it remains to be seen whether these changes will be accompanied by additional funding to support public engagement activities, or whether they will simply add another expectation for already overburdened researchers.

2. University responses: Some universities have begun to recognize voluntary work in tenure and promotion decisions, but this remains the exception rather than the rule. The Nature study could prompt more institutions to formalize the value of unpaid contributions, but this will likely face resistance from traditionalists who argue that research output should remain the primary metric for career advancement.

3. Equity initiatives: The study’s findings on the benefits of voluntary work for underrepresented groups could lead to targeted programs to support scientists from marginalized backgrounds in accessing these opportunities. For example, universities might create funded fellowships for public engagement or mentorship roles, ensuring that these opportunities are not limited to those who can afford to work for free.

4. Labor rights in academia: The study’s warnings about the risks of unpaid labor could reignite debates about academic precarity and the exploitation of early-career researchers. Advocacy groups, such as the University and College Union (UCU) in the UK and the American Association of University Professors (AAUP), may push for new labor protections to ensure that voluntary work does not become a de facto requirement for career advancement.

5. Global disparities: The study highlights the role of voluntary work in helping scientists from LMICs access international networks, but it also raises concerns about global inequities in who can afford to engage in unpaid labor. Future research may explore whether funding agencies and universities can redistribute resources to support public engagement in low-resource settings, rather than relying on the goodwill of individual researchers.

Conclusion

The Nature study provides the most comprehensive evidence to date that voluntary work in science can deliver real career benefits, from higher grant success rates to expanded professional networks. For many scientists—particularly those from underrepresented groups—unpaid contributions to public engagement, mentorship, and community-based research have become a critical pathway to visibility and opportunity in an increasingly competitive academic landscape.

However, the study also serves as a cautionary tale. The growing expectation of voluntary work risks **exploiting the goodwill of
