Helpers usually need the task, time window, completion state, and escalation contact—not the diagnosis behind it. Keep sensitive context with the coordinator and reveal more only when the person receiving care has approved it.
Ask for stories about the last three surprises rather than “everything you know.” Concrete incidents reveal hidden dependencies, and the outgoing volunteer can mark each detail as seasonal, safety-critical, or merely convenient.
Fairness should be measured over a season, not one Saturday. Give each task an effort band, let people opt into eligible bands, and publish a rolling balance so an imperfect week can correct itself later.
Keep the public record event-sized: task offered, person accepting, completion, and one note for the next visit. Weather can trigger suggestions, but volunteers should always be able to swap without explaining private circumstances.
