Social movements get their start outside the social institution an aspect of which they aim to change or resist. This holds for any institution. Nevertheless, these movements do help constitute the macro context of which every institution is a part. This said, some movements are organized to the extent of being directed by one or more formal organizations, whereas other, usually newer, movements lack this organizational base. Volunteers are vital in both types. In other words, most social movements aim for change or resistance to change that has little or nothing to do with leisure, but nonetheless rely heavily on people for whom participation in them may be leisure. Here they act as volunteers (see Stebbins, 2002, Chapter 7).
