本文旨在瞭解工作者知覺屈就(知覺「高才低就」及知覺「才非所用」)、敬業貢獻對離職意圖之影響。本研究透過問卷調查法,以台灣全職上班族為樣本,透過網路及紙本方式發放問卷,共回收292份有效問卷。實證結果發現:知覺「高才低就」及知覺「才非所用」等二項因素分別對敬業貢獻皆具有負向的顯著影響,而敬業貢獻對離職意圖具有負向的顯著影響。另外,透過階層迴歸分析發現,敬業貢獻對於知覺「高才低就」、離職意圖具有完全的中介效果,而敬業貢獻對於知覺「才非所用」、離職意圖具有部份的中介效果。最後,針對研究的結果,提出了具體的實務建議與未來研究建議。 The purpose of this study is to examine how perceived overqualification (including perceived overeducated and mismatch) and work engagement impact on employees’ turnover intention.
