Volunteer requirements attached to welfare benefits could help small business owners greatly in these times when everybody thinks every job should pay 20 an hour plus.
You would have to require the business does not over use the volunteer system and still keep hired hands. You would also have to make it easier for business owners to use volunteers on their insurance policies.
Volunteers could volunteer their time in a variety of wasy including labor, office, or even child care ( with proper background checks of course)
