企業透過聘用工讀生可以彈性調整人力結構，又可以節省成本。然而工讀生由於社會經驗的不足、缺乏磨練與教育訓練，其與客戶或公司人員互動時，可能產生負面人際互動知覺。因此本研究目的主要探討工讀生與上司、同事、顧客互動時所產生的負面人際互動知覺類型。首先，以開放式問卷詢問研究對象，發展出相關題項，再以25位工讀生為對象，進行Q分類。研究結果發現工讀生負面人際互動知覺類型包括：不公平對待知覺型、代罪羔羊知覺型、未獲信任知覺型與政治鬥爭知覺型四類。上述類型可協助企業瞭解工讀生的負面人際互動知覺問題，使管理階層協助其改善職場負面人際互動問題，以提昇管理效果。

Numerous enterprises hire part-time workers to achieve the strategic goals of flexible human resource structure and cost reduction. However, because of insufficient social experiences and a lack of appropriate training and education, part-time workers often have negative interpersonal interaction perceptions when interacting with external customers and internal personnel. This study identified the types of negative interpersonal interaction perceptions that occur in the relationships between part-time workers and their superiors, colleagues, and customers. This study developed a list of relevant questions using an open-ended questionnaire and subsequently conducted Q-sort processes using 25 part-time workers. The results showed 4 types of negative interpersonal interaction perceptions: unequal treatment perception, scapegoat perception, untrusted perception, and political struggle. Based on the identified types, managers can understand the negative interpersonal interaction perception problems and implement strategies to mitigate these problems and enhance management performance of flexible human resource structures and cost reduction.
