"We can't find enough volunteers" is one of the most common complaints in church leadership, and it's rarely actually about a shortage of willing people. It's usually about an unclear ask, an unclear time commitment, or no follow-up after someone says yes.
Replace vague, general appeals ('we need more volunteers!') with specific ones: 'we need one person to greet at the 9am door for four Sundays.' Specific, bounded asks get more yeses than open-ended ones, because people can actually picture saying yes to them.
Onboarding matters as much as recruiting. A volunteer who shows up their first Sunday with no idea where to stand or what to do rarely comes back a second time — a five-minute walkthrough beforehand prevents most of this attrition entirely.
Finally, say thank you specifically and publicly, not just generally. 'Thanks to our volunteers' from the stage is easy to tune out; a handwritten note or a specific shoutout by name goes much further toward someone volunteering again next season.
