員工具有工作熱情對企業與員工本身都有正面效益，因此，如何提高員工的工作熱情，是企業必須要關心的議題。然而，過去雖有研究指出直屬主管的行為對於員工工作熱情具有一定的影響力，但少有文獻有進一步的探討，因此，本研究希望從主管行為的角度出發，深入探討哪些主管行為有助於提高員工的工作熱情。本研究分成兩階段進行，第一階段透過文獻回顧，以及訪談五位實務界的專家，瞭解有哪些主管行為能提高員工工作熱情，並依照文獻資料與訪談結果編制主管行為問卷。第二階段使用第一階段發展的問卷進行量化驗證，以確認文獻與專家們提到的主管行為是否對員工工作熱情有正向的影響。 本研究問卷共蒐集到259個有效樣本，來自六家電子資訊業與兩家金融業，受測者皆為在職超過六個月以上的正職員工。本研究以階層迴歸分析確認主管行為變項與員工工作熱情變項間的關係，結果發現主管行為的「積極的指導與關懷」對和諧式熱情有正向影響；另外，主管行為的「以員工為中心的激勵」對和諧式熱情與強迫式熱情皆有正向的影響。 / Work passion can have noticeable beneficial effects on both employees and employers. Therefore, raising the employee’s passion for work is one of the key points which enterprises need to concern. There are some researches indicate that the behaviors of direct supervisors can impact on work passion of employee but the relationship remains unexplained. Here we’d like to investigate that from supervisor’s perspective, what kind of behavior from managers can enhance the work passion of employee. In the first part of this research, we have gone through reviews from both references and interviews of 5 managers from industry to conclude the specific behaviors which influence the work passion. Then we have induced a questionnaire according to the factors. Later, we have measured quantitatively from the survey and we have verified the relationships between supervisor’s behavior and employee’s work passion. We have collected 259 effective samples from 8 companies including IT, electronics, and financial industries. The subjects need to be a full-time employee for at least 6 months. This research takes hierarchical regressions to analyze the relationships between supervisors’ behaviors and employee’s work passion, and we found the “aggressive instruction and care” have productive influence on the harmonious passion. Besides, “employee-oriented encourage” also have affirmative effect on both harmonious passion and obsessive passion of workers.
