This thesis is a study of older volunteers and their feelings of being valued and of worth within that role. The perceptions of older volunteers and their managers within three participating non-government organisations, government and organisational policy documents and relevant legislation and literature in the fields of ageing and volunteering provided data for the research. Changing political, economic and social conditions together with ageing of the Australian population have resulted in human services being increasingly contracted to non-government organisations. This in turn has resulted in more services than hitherto being delivered by volunteers many of whom are older people. Population ageing implies that there will be an increasing need for human services provision in the first half of the twenty first century. Whether there will be sufficient volunteers to maintain these services will depend at least in part on the responsiveness of organisations to their volunteer base and the effectiveness of their recruitment strategies. This research indicates that a sense of mastery over their circumstances is critical to volunteer satisfaction. Volunteers discussed their perceptions of maintaining control over their circumstances through the process of initiating volunteering arrangements and negotiating role changes in response to their changing health or abilities. Managers recognised the need to be responsive to the changing abilities of older volunteers and identified strategies for maintaining the volunteer contribution. Management style and in particular communication emerged as integral to volunteer satisfaction and an awareness of and responsiveness to differing motivators was important, particularly in relation to social networking and making a worthwhile contribution as a source of feeling valued.
