Professionals or Volunteers to Kchag?

According to Wikipedia,
"Volunteerism is the willingness of people to work on behalf of others without the expectation of pay or other tangible gain. Volunteers may have special training as rescuers, guides, assistants, teachers, missionaries, amateur radio operators, writers, and in other positions. But the majority work on an impromptu basis, recognizing a need and filling it, whether it be the dramatic search for a lost child or the mundane giving of directions to a lost visitor.[citation needed] 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."
Wikipedia adds another term, which is skills-based volunteerism. According to this Encyclopedia,
"skills-based volunteerism is a term used to describe volunteering where the volunteer uses their professional skills. This is in contrast to generic volunteerism where specific skills are not necessary."
