It is someone who chooses to act in recognition of a need, with an attitude of social responsibility and without concern for monetary profit. Not everything done by volunteers is labeled as volunteering. In a school, it might be called service learning, community service or an internship. In professional society, it may be referred to as pro bono. In the streets, it is called neighbourliness. At church it is referred to as lay ministry. In a group of peers, it may be self-help and in a protest it would be called activism.
