Spillover of Interpersonal Conflicts From Work into Nonwork: A Daily Diary Study
This study among a heterogeneous sample of employees expands the Job-Demands (JD-R) theory by examining how interpersonal conflicts at work–task and relationship conflict–spillover into the nonwork domain on a daily basis. We hypothesized that daily personal resources can buffer the daily negative spillover of interpersonal conflicts from work into the nonwork domain. A total of 113 employees (n 565 occasions) filled in a daily diary questionnaire in the evening before bedtime over 5 consecutive working days. Results of multilevel analysis showed that the presence of daily personal resources is essential to buffer the spillover of interpersonal conflict at work to the nonwork domain. Specifically, on days that employees were not very optimistic or resilient, interpersonal conflicts resulted in higher strain-based work–life conflict experiences. These findings contribute to the JD-R theory and show how the unfavorable effects of daily interpersonal conflicts in the work domain may be avoided in the nonwork domain through enhancing personal resources. We discuss the implications for theory and practice.
