How to stop no-shows on event staff

How do you stop event staff from no-showing?

Most no-shows come from unclear commitment and no reminder. Cut them by having staff claim a specific role themselves, so it's their commitment, not an assignment nobody confirmed. Automatic reminders go out before the event, and if someone drops, the next person already waiting for that role is a tap away to approve, so a no-show doesn't leave the role empty.
