Describe the actual commitment

Name the task, expected time, location, and support available. A specific two-hour role is easier to consider than an open-ended request to help more.

Offer a first step

Let someone try a role alongside an experienced volunteer. They can learn what the work involves before committing to a regular rhythm.

Build a sustainable rota

Ask about availability and boundaries. Keep a simple way to swap a shift, and avoid treating every cancellation as a lack of commitment.

Close the loop

Thank people for the concrete thing they did. Ask what would make the role easier next time and use that feedback when planning the next gathering.
