面對電信產業市場及科技快速變遷、競爭激烈的環境,主管需運用較多的轉換型領導才能真正滿足員工的需求。因此,個案公司希望藉此瞭解主管之轉換型領導行為對員工工作滿足及組織承諾的影響,並進一步探討轉換型領導是否會透過工作特性知覺以影響工作滿足及組織承諾。本研究以一般員工為抽樣對象,共發放問卷350份,回收302份,有效問卷共282份。其結論如下: 1. 員工知覺主管的轉換型領導行為愈顯著,其工作重要性、自主性、回饋性的知覺會愈高 2. 員工知覺主管的轉換型領導行為愈顯著,其內在滿足程度愈高,且此影響部份是透過工作重要性、自主性知覺之中介效果 3. 員工知覺主管的轉換型領導行為愈顯著,其外在滿足程度愈高,且此影響部份是透過自主性、回饋性知覺之中介效果 4. 員工知覺主管的轉換型領導行為愈顯著,其價值承諾愈高,且此影響部份是透過工作重要性、自主性知覺之中介效果 5. 員工知覺主管的轉換型領導行為愈顯著,其努力承諾愈高,且此影響部份是透過工作重要性、自主性、回饋性知覺之中介效果 6. 員工知覺主管的轉換型領導行為愈顯著,其留職承諾愈高,且此影響部份是透過工作重要性知覺之中介效果 To face the critical and highly competitive environment in telecommunication industry, the manager has to unroll his/her transformational leadership behaviors to improve the employees’ motivations and satisfactions.
