This study identifies the factors affecting volunteer retention and engagement. A dearth of research has focused on volunteering for not-for-profit organisations. These organisations are involved particularly in raising funds through public benevolence. There have been rising trends of not-for-profit organisations around the world while the number of volunteers decreases. Information on the factors influencing volunteer retention and engagement is expected to support the management of not-for-profit community services. Therefore, this study uses a case study of a not-for-profit organisation to identify the factors contributing to volunteer retention and engagement. The interview data is analysed using thematic data analysis. Benightedness, communication, management support, volunteer skills and volunteer participation in management decision making are associated with volunteer retention and engagement. These findings are expected to enhance the operation process of not-for-profit Community Fund Management Organisations. Future research is suggested to enhance the management of volunteers in other types of not-for-profit organisations.

本研究确定了影响志愿者保留和参与的因素。缺乏研究集中在为非营利组织提供志愿服务。这些组织特别参与通过公益活动筹集资金。世界各地的非营利组织呈上升趋势，而志愿者人数却在减少。有关影响志愿者保留和参与的因素的信息预计将支持非营利社区服务的管理。因此，本研究使用一个非营利组织的案例研究来确定有助于志愿者保留和参与的因素。访谈数据采用专题数据分析法进行分析。昏昏欲睡，沟通，管理支持，志愿者技能和志愿者参与管理决策与志愿者保留和参与有关。这些调查结果有望改善非营利性社区基金管理组织的运作流程。建议未来的研究加强对其他类型非营利组织志愿者的管理。
