VOLUNTEERISM by WIKEPEDIA

Volunteerism is the willingness of people to work on behalf of others without being motivated by financial or material gain. Volunteers may have special training as rescuers, guides, assistants, teachers, missionaries, amateur radio operators, writers, and in other positions. But the majorities work on an imprompt basis, recognizing a need and filling it, whether it be the dramatic search for a lost child or the everyday giving of directions to a lost visitor.In economics, voluntary employment is unpaid employment. It may be done for altruistic reasons, for example charity, as a hobby, community service or vocation, or for the purpose of gaining experience. Some go so far as to dedicate much of their lives to voluntary service.
