Digital connectivity for work after hours: Its curvilinear relationship with employee job performance
研究了下班后使用数字技术处理工作（数字连接）与员工工作绩效的关系，发现两者呈倒U型曲线，适度的数字连接通过提升社会资本和减少情绪耗竭促进绩效，但过度则有害。
Abstract Using digital technologies for work‐related matters during nonwork time is an increasingly common behavior in contemporary workplaces. Despite the prevalence of digital connectivity (DCON) in today's organizations, its implications for employee job performance remain under‐specified. Drawing on conservation of resources (COR) theory and the “too‐much‐of‐a‐good‐thing” (TMGT) meta‐theoretical principle, we theorize that DCON has an inverted U‐shaped relationship with employee job performance through the mediation of social capital development (SCD) and emotional exhaustion (EE). The results of two studies with different designs support our theoretical expectations. Specifically, we found that increases in DCON associate with higher SCD, lower EE, and higher job performance up to an inflexion point, after which more DCON has detrimental effects. The theoretical and practical implications of the findings are fully discussed.
