不要太晚打擾我！探討下班後工作訊息接收時段對於工作與家庭的影響：疆界管理策略的調節效果

Do Not Disturb Me Too Late! Exploring The Impact of The Time of Receiving Work-Related Message after Work on Work and Family Outcomes: The Moderating Effect of Differential Permeability Tactic

智慧手機等行動裝置促使人們聯絡愈來愈快速、彈性，但這些工作相關的即時通訊或email也使得個人在工作與家庭生活的界線愈加模糊，對於員工下班後的生活造成干擾。因此，本研究欲探討員工下班接收工作訊息的時段對於工作和家庭的影響，以及可能的調節變數。我們採用經驗抽樣法，請受試者連續五天填寫每日問卷，最後共獲得84位受試者的339筆每日早晚的配對資料。透過多層次線性模式分析，結果顯示接收工作訊息的時段愈晚，會增加負向情緒，並導致隔天上班時較低的敬業貢獻，但不會導致當晚較多的工作家庭衝突。此外，結果亦顯示若個人採取差別滲透的疆界管理策略，有助於緩和較晚收到工作訊息對於負向情緒的影響，也會調節接收工作訊息時段透過負向心情對隔天敬業貢獻之間接效果。本研究並依結果提出理論與管理意涵。

Mobile devices facilitate our communication by promoting availability and flexibility of communication. However, work-related messages during off-job time can blur the boundary between work and family life. In this study, we investigate how the off-job time at which an employee receives a work-related message can affect family and work outcomes. We also explore potential moderators of these effects. Using an experience-sampling method involving morning and evening surveys, we collected data from 84 employees over five consecutive workdays. To analyze the data from the 339 valid surveys, we conducted hierarchical linear modeling analysis. The results show that the later in the evening an employee received a work-related message, the more negative his or her mood would be at the time and the less engaged he or she would be at work the next morning. However, the indirect effect of message-receipt time on work–family conflict was not significant. We did find that employees’use of a differential permeability tactic helped them mitigate the effect of message-receipt time on negative mood and also helped them mitigate the indirect effect that message-receipt time, via negative mood, had on work engagement.
