This report gives diverse perspectives on volunteering, based on interviews with a range of stakeholders. It makes the case for involving volunteers in work with offenders. If you work for a Voluntary and Community Sector (VCS) or a campaigning organisation, the information here might help you prepare funding applications, to think about service design, and to write publicity materials. If you work for a statutory or private sector organisation, the information here shows you some examples of how the involvement of volunteers can help you to carry out your work more effectively.
