[TheThinkTank] Volunteer Background Checks

At Broke Spoke (Lexington) we are working to improve our volunteer process and how we create shift managers and dull out keys.

What type of checks (if any) do other shops use prior to handing out shop keys to volunteers?

Any background, employment history, references, etc? Some of these might be barriers as we work with a lot of folks who are in recovery centers, shelters, etc.

Any help is greatly appreciated.

Cheers Tim
