職場情感關係一直是每位上班族在工作場域中會經歷的現象。隨著企業組織的多元化，工作已變得快速化、複雜化與跨部門化，員工所接觸的對象已並非都是來自同部門的同事和主管，也有來自不同部門的成員。雖然過往研究有討論過其他場域如家庭、學校等成員的情感關係，但職場關係應或許與這些場域一樣會有正向情感關係之發現。
本研究藉由半結構式的質性訪談訪問了30位在職的上班族，探討在跨部門專案團隊裡，擁有專業能力同質性和網絡封閉性如何影響團隊成員的情感關係。研究結果顯示當跨部門專案團隊的團隊成員彼此擁有專業能力同質性，在情感互動上會有正向情感關係，例如在溝通上會比較和諧、信任對方的工作表現，以及支持其專業意見；而在網絡封閉性的部分，發現到當團隊成員與自己擁有共同要好的同事，彼此也有情感性社會資本的正向情感關係，像是會主動願意認識對方來增進彼此的熟識度，以及在專案上會願意與對方採取合作關係，但卻有過半比例以上的受訪者表示不會去信任對方的工作表現。

Emotional relationships in the workplace have always been a phenomenon that every worker will experience. Especially with the diversity of corporate organizations, work has become faster, complex, and cross-functional. Employees are not always in contact with colleagues and supervisors from the same department, but also interact with some members from different departments. Although previous researches have discussed the emotional relationships of members in other fields such as family and school, the relationship in workplace may be found to have the same positive emotional relationships as these fields.

In this study, 30 office workers from different industries were interviewed through semi-structured interviews of qualitative research to examine how homophily of professional competencies and network closure affect the emotional relationships of team members in cross-functional project team. The results of the study revealed when team members with homophily of professional competencies in cross-functional project team, they have positive emotional relationships, such as more harmonious communication, trust in their job performance, and support their professional opinions. And in the part of network closure, we also found when team members have close colleagues in common with themselves, they have positive emotional relationships of emotional social capital and that causes being willing to get to know each other to increase their familiarity, and willing to cooperate with each other on cross-functional project team, but more than half of the respondents said they would not trust in each other’s job performance based on network closure.
