本研究旨於探討工作滿意度、留任意願及組織公民行為之關係,並進一步檢驗職場友誼之調節作用。此研究採問卷調查法蒐集資料,以具有全職工作經驗之在職人員為研究對象,共回收435份問卷,經資料清理後,剔除無效的樣本8份,最終有效的樣本共427份。研究工具包括工作滿意度、組織公民行為、職場友誼及留任意願等量表,並使用李克特五點量表作測量。資料分析方法包含了描述性統計分析、信度分析、皮爾森相關分析,以及階層迴歸分析與調節效果檢驗。 研究結果顯示:(1)工作滿意度與留任意願具有顯著正向關係;(2)工作滿意度與組織公民行為具有顯著正向關係;(3)職場友誼對工作滿意度與留任意願之關係未具有顯著調節效果;(4)職場友誼對工作滿意度與組織公民行為之關係具有顯著調節效果。 最後,本研究亦針對研究限制提出說明,並提供未來研究方向之建議,以供後續相關研究參考。;This study aims to examine the relationships among job satisfaction, retention intention, and organizational citizenship behavior as well as the moderating effect of workplace friendship.
