Volunteers don’t send resignation letters

Your movement is probably losing people right now. You just won’t find out for another six months.

In a company, someone who leaves at least hands in their notice. You get a letter. A date. An awkward goodbye cake. In a movement you get nothing. People stop replying in the group chat. They skip one meeting, then two. They’re “busy this month.” And one day you realise you haven’t seen them since spring.

No resignation letter or exit interview. Just silence.

I know this from both sides. When I was volunteering 30 hours a week on top of a full-time job, I was the one drifting toward the exit. I just didn’t admit it yet. Later, as a leader, I watched good people slip away and told myself they were busy. They weren’t busy but they were done, and I was the last to know.

The numbers are worse than you think

Nonprofit staff turnover runs around 20 to 22 percent a year. Other sectors sit around 12 to 13 percent (Social Impact Architects, 2026). In a 2024 survey by the Social Impact Staff Retention Project, 67 percent of nonprofit employees said they were job hunting or would be within a year. Sixty-seven percent.

Volunteers are worse still. The average volunteer retention rate sits around 65 percent. One in three volunteers doesn’t come back next year. Some organisations lose more than half. Often after one or two shifts, gone without a word.

What the research says about why people leave

This isn’t business data stretched over our sector. Researchers have been asking volunteers and activists directly for years. Three findings stand out.

Leaving is organisational, not personal. The UK’s largest study of the volunteer experience, NCVO’s Time Well Spent, found that when volunteers stop, the most common answer they give is “no reason in particular.” They can’t even name it. But when researchers dug deeper, in one national study of volunteer police officers, the top three reasons for wanting to quit were being under-used, not being supported, and not feeling appreciated. Not “too busy.” Not “lost interest.” Under-used. That one deserves a moment. People don’t only leave because you ask too much. They also leave because you ask too little of what they have to offer.

Stress is climbing the list too. The share of UK volunteers naming stress as a reason to stop rose from 9 percent in 2019 to 14 percent in 2023. More volunteers report unreasonable expectations.

Every volunteer signs a contract you never see. Researchers call it the psychological contract. It’s the unspoken deal about what someone will give and what they’ll get back. Purpose, growth, appreciation or community. Studies show this deal forms in the very first conversations, before someone even starts. When volunteers feel it’s been broken, their satisfaction drops. So does their intention to return.

There’s a cruel twist in this research. When people feel the mission itself is being let down, committed volunteers first work harder. They compensate. They carry more. And when nothing changes, they burn out and leave. If you’ve ever watched your most dedicated person go from unstoppable to gone in what felt like a week, it wasn’t a week. The burnout studies confirm it. People under role stress don’t quit right away. They quit once the exhaustion is complete. There’s a long, visible road between cause and exit. Most leaders aren’t looking at it.

People stay for who they become, not for the cause. Political scientist Hahrie Han compared high-engagement and low-engagement chapters of the same organisations. Her finding was blunt. Most groups mobilise. They activate people who already care, use them for a task, done. Transactional. The groups that keep people organise. They invest in the people themselves. Relationships, skills, real responsibility, a sense of how their work fits the bigger picture. Commitment to a cause alone doesn’t hold people. Community does, and so does growing into the role of activist.

Marshall Ganz, the organiser behind the United Farm Workers and Obama’s volunteer operation, adds the missing piece. Commitments to each other beat commitments to an idea. And structure decides whether those commitments can form at all. His research with the Sierra Club found the classic failure pattern. One heroic leader carries everything. When that collapses, groups swing to no structure at all, which is chaos. What worked instead were small teams of five to seven people with a shared purpose, clear norms, and real roles.

Notice what just happened. The volunteer surveys, the burnout studies, and the organising research all point at the same culprit. It is not about the people or their passion. It is about the way the movement is built.

“But we’re not a company”

True. And that makes it harder for you, not easier.

An employee has a salary keeping them in the room while things are bad. A volunteer has nothing holding them except the experience itself. The moment the experience turns into chaos, guilt, and unread messages, they’re free to walk. And they do. Quietly, politely, without ever telling you why.

Researchers who study activist burnout call it one of the biggest threats to the survival of movements. Paul Gorski’s work shows activists don’t burn out mainly because the work is hard. They burn out because of what happens inside movements. Feeling solely responsible, isolation. Cultures where exhaustion is worn as a badge of honour. This is something I experienced as well. His answer isn’t more self-care. It’s community care. Burnout becomes something the movement handles together, not something each person manages alone in the margins.

When an experienced activist burns out, the damage compounds. Younger people lose a mentor, which makes them more likely to burn out too. That is an expensive treadmill. The problem is that we just don’t have a recruiting budget to restart it. We just work harder. Which is how the next person burns out.

The better question

When another good person disappears, most movement leaders ask how to find new volunteers.

Wrong question. Recruitment doesn’t fix retention. If the way your movement works grinds people down, every new volunteer steps onto the same treadmill. They arrive full of fire. They hit the same chaos. They drift out the same silent door. And you’re back at the info evening, smiling, recruiting their replacement.

The better question is what people are leaving from. Here’s how you find out, in three steps. They get harder as you go.

Step one, count

Not the people who joined this year. The people who were there last year and still are. That number is your real health check. If one in three is gone, your movement isn’t growing. It’s leaking. You can’t fix a leak you haven’t measured.

Step two, ask

Ask the ones still with you one question. “What would make you stay another year?” Ask it before they go quiet, not after. The silence in your group chat is data too. Start reading it.

Then go find the people who already left. “What made you leave, and was there something that would have made you stay?” Their answers will be uncomfortable. They’re also the cheapest advice you’ll ever get.

Step three, look at yourself

This is the hardest one, because you’re examining the system you created.

Start with your own behaviour. I spent years on the treadmill before someone told me the most valuable thing I’ve ever heard. “You’re replaceable, Emmy.” It forced me to stop asking how I could carry more. I started asking why everything depended on me carrying it at all and changed my perception of what good leadership is. I also started treating exhaustion as a signal instead of a badge. And I made sure people saw me rest. Because people copy their leader’s behaviour. If the leader never takes a break, everyone else learns the real rule. You have to perform to be included.

Then look at the organisation itself, with the same honesty. Is onboarding actually arranged, or do new people have to guess their way in? Does anyone get real ownership, or do all decisions still pass through you? Who gets heard, and who has quietly learned that speaking up changes nothing? Remember, the unspoken contract forms in the first conversation. Most movements break it in the first month, without ever noticing. 

What the three steps add up to

Count, ask, look at yourself. Do that and you’ll see what the research already told you. People rarely leave because of the cause. They leave because of how the movement is built and led. Who feels ownership. Who feels heard and belonging to the group. What happens before anyone even starts. Remember, the unspoken contract forms in the first conversation. You might as well make it a real one.
