The number of firms supporting work from home has risen dramatically as advances in communication technology have fundamentally transformed the way humans cooperate. A growing literature addresses working from home, but focuses only on individual workers, overlooking potential influence of co‐worker engagement. Our aim is to study the influence of co‐workers working from home on individual and team performance. We use unique data from a large‐scale survey involving nine European countries, 259 establishments, 869 teams and 11,011 employees to show that the impact of working from home by co‐workers on performance is considerable and has remained hidden in past studies because they did not account for co‐worker effects. While working from home may be useful for some workers, it does bring issues for them as well. Specifically, we demonstrate that co‐workers working from home negatively impact employee performance. Moreover, team performance is worse when more co‐workers are working from home.

在家工作的同事以及个人和团队绩效

随着通信技术的进步从根本上改变了人类合作的方式，支持在家工作的公司数量急剧增加。越来越多的文献讨论了在家工作的问题，但只关注个体员工，忽视了同事敬业度的潜在影响。我们的目标是研究在家工作的同事对个人和团队绩效的影响。我们使用来自一项涉及 9 个欧洲国家、259 个企业、869 个团队和 11,011 名员工的大规模调查的独特数据来表明，同事在家工作对绩效的影响相当大，并且在过去的研究中仍然被隐藏，因为他们不考虑同事效应。虽然在家工作可能对某些员工有用，但也给他们带来了问题。具体来说，我们证明同事在家工作会对员工绩效产生负面影响。此外，当更多同事在家工作时，团队绩效会更差。
