Well-managed volunteers are assets that charities insist they cannot do without. Nevertheless, few charities publish the value of their volunteers' efforts in annual reports. Charities' current practices in communicating volunteers' value reflect the regulatory environment, but not their increasing professionalization. Valuing volunteers can assist charities in services planning and to build their reputation in their communities. However, charities' managers must also accept that judgement is required in negotiating the sensitive nature of defining volunteers' value.
