The rota is not the problem. The rota is usually a reasonable rota. What fails is everything around it.
What a roster is actually for
Most clubs treat a duty roster as a way of filling slots. It is better understood as a way of making a gap visible early enough that somebody can do something about it.
Those sound similar and they lead to completely different designs. A roster built to fill slots gets published once, in February, and is treated as settled. A roster built to surface gaps gets looked at every week, and the interesting question it answers is not "who is on duty on the 14th" but "which of the next six Saturdays currently has no instructor".
The second question is answerable in time to fix it. The first is only ever answered on the morning of the 14th, in the clubhouse, by whoever turned up.
A useful test: if your duty roster were deleted tomorrow, how long before anyone noticed? If the answer is "the next flying day", it was never doing the job — the club was running on the same six people turning up regardless, and the roster was documentation of that, not a cause of it.
Why people do not volunteer
It is rarely apathy, and treating it as apathy is how committees make it worse. Four causes come up again and again, and all four are fixable.
The ask is unbounded
"We need more help on Saturdays" is not something a person can say yes to. It has no start time, no end time, and no definition of done. A member who says yes to it has agreed to an unknown quantity of work, and the reasonable response to an unknown quantity of work is to look at your shoes.
"Can you run the launch point from 10 until 1 on the 22nd? Someone takes over at 1" is a different proposition entirely. Same work, bounded. People say yes to bounded things.
They do not know they are allowed
New and mid-tenure members frequently believe duties are for people who have been around longer, know the tractor, or hold something they do not hold. Nobody has told them otherwise, because to everyone who has been there ten years it is obvious.
Every duty should have a written line on who can do it and what, if anything, you need first. Half of them will turn out to need nothing but a briefing.
The guilt cycle
When a roster is thin, the standard response is an appeal at the AGM about how the same people do everything. This is aimed at the people who are not there. The people it actually reaches are the six who already do everything, who now feel both tired and criticised.
Guilt recruits nobody and costs you goodwill with the volunteers you already have.
Asking the room instead of the person
A general appeal to a mailing list converts at close to nothing. A specific request to a named person, for a named date, converts remarkably well — most people say yes when actually asked, and most have never actually been asked.
This is the single highest-yield change most clubs can make, and it costs an hour of someone's week.
Measure concentration, not coverage
Most clubs track whether days were covered. Coverage tells you the club survived. It does not tell you at what cost, or how close you are to it stopping.
The number worth tracking is concentration:
What share of duty days last season were worked by our top six volunteers?
If that number is 70% or higher, the club is one house move, one new job and one bad back away from not being able to operate. That is not a volunteering problem to raise at the next AGM; it is an operational risk that deserves a plan.
The companion number is just as useful and slightly uncomfortable: how many active flying members did no duty at all last season? In most clubs it is a larger number than the committee expects, and it is a list of people who have never been asked directly.
Three models, and when each works
| Model | Works when | Fails when |
|---|---|---|
| Fixed rota — assigned in advance for the season | Membership is stable and duties need specific qualifications | People's lives change and swaps are hard, so the rota silently decays |
| Self-signup — members claim days | Enough members, and gaps are visible far enough ahead | Everyone claims the good weather and nobody claims October |
| Hybrid — critical roles assigned, the rest open | Most clubs, most of the time | Nobody owns chasing the assigned roles when someone drops out |
The hybrid wins for most clubs because the constraint is almost never "ground crew". It is instructors and tow pilots — a small pool with real qualifications, where a single dropout cancels the day. Those get assigned and chased. Everything else can be self-service.
The things that actually work
- Publish further ahead than feels necessary. A gap six weeks out gets filled by somebody rearranging a weekend. The same gap on Thursday gets filled by one of the same six people, again.
- Make swapping easy and blameless. Most no-shows are not unreliability; they are somebody who could not face admitting they had a conflict. If swapping requires emailing an officer and explaining yourself, people will quietly not turn up instead.
- Ask named people for named dates. Rotate who you ask so the same willing few are not asked first every time — which is precisely how the willing few became the only six.
- Say thank you where people can see it. Not a trophy at the annual dinner. A line in the weekly email naming who ran the launch point. It costs nothing and it is the main reason people do it again.
- Give every duty a written half-page. What time to arrive, what to do, who to ask. The barrier to a first duty is almost always "I don't know exactly what's involved and I don't want to look stupid."
When the honest answer is to fly fewer days
Sometimes a club genuinely does not have the people. Every retention trick has been tried, the concentration number is 80%, and the six are running out.
At that point the choice is not between a better roster and a worse one. It is between operating fewer days properly and operating more days on the goodwill of people who are close to stopping. Clubs are very reluctant to choose the first, because dropping a flying day feels like decline.
It usually is not. Six well-staffed days do more flying, more safely, with better instruction, than ten thin ones — and thin days are where people get tired, corners get cut, and the volunteers you have left decide it is not fun any more. A club that deliberately consolidates is in better shape than one that quietly burns through its last six.
Where the record-keeping comes in. Nothing above needs software. The concentration number, the never-volunteered list and the six-weeks-ahead view all come from data most clubs already have, scattered across a sign-in sheet and somebody's memory. Getting them into one place is what makes the questions answerable — and it is a large part of what GliderOps does. But the questions are worth asking with a spreadsheet and a shoebox of sign-in sheets, and the answers will be uncomfortable either way.
