Frequently asked questions
How are shifts assigned?
A shifts sheet lists slots with capacity. When a volunteer picks a preferred slot, the workflow checks remaining capacity and assigns them if there's room, decrementing the count. If full, it offers the nearest open slot instead.
Can it handle cancellations?
Yes — a cancel link frees the slot (incrementing capacity) and notifies the coordinator, who can then promote a waitlisted volunteer. Making changes easy keeps the schedule accurate right up to the event.
