志工對學校而言是一個很重要的資源，許多家長因為子女在學校就讀而到學校擔任志工，子女從學校畢業後，就會離開，但有些則會繼續留任。本研究旨在從認真休閒的理論探討志工會選擇繼續留任的想法。
研究採取質性訪談方法，訪問南投縣光華國小志工媽媽合唱團六位年資在三年到十八年的志工。藉由訪談大綱與志工們做深度對話後，整理與歸納分析結論如下：
1、志工媽媽合唱團的團員在來校擔任志工前，就已曾在其他地方擔任志工服務，他們加入志工媽媽合唱團的動機，雖然也有利他動機，但也有很大部分的利己動機。
2、志工媽媽合唱團的團員可以獲得自我充實、自我實現、自我表現、自我形象、自我滿足、自我重建、與化阻力為助力的個人休閒效益。
3、志工媽媽合唱團的團員可以獲得社交互動、團體成就、與團體認同的社會休閒效益。
