Summary Commuting is a central activity of life that cuts across industries and occupations. Because a large majority of employees commute to work, organizational scholars have long been interested in the relevance of commuting to organizational life. This interest forms the foundation of a research tradition to understand commuting spillover, which reflects interrelationships between commuting and work experiences. Unfortunately, commuting spillover investigations have historically been fractured across publications in the management, psychology, transportation, and ergonomics communities, impeding understanding of the nature and implications of commuting spillover for organizational stakeholders. We conduct a systematic review to identify what is known and unknown about commuting spillover, attending to both between‐ and within‐person approaches to studying this process. This effort yields five major conclusions emerging from the commuting spillover literature, as well as the identification of two frequently investigated topics that have yielded few clear findings within this research base. This knowledge synthesis is used to develop an agenda for the next wave of commuting spillover research that aims to extend this research base while resolving inconsistencies observed in past research. We conclude with calls for methodological advancement and theory development on the commuting spillover topic.

While many employees read and respond to work-related e-mails in the evenings after work, the mechanisms through which after-hours e-mailing influences wellbeing remain poorly understood. In particular, there has been limited consideration of whether different characteristics of after-hours e-mails (frequency, duration, perceived tone) may trigger work-related rumination that influences employee wellbeing at bedtime (i.e., the end of the post-work period). To address this gap in the literature, data were collected from 59 employees during a 5-day daily survey period. We expected after-hours e-mail frequency, duration, and perceived tone to indirectly relate to employee vigour and fatigue at bedtime (two common well-being criteria) via affective rumination and problem-solving pondering (two major forms of work-related rumination). Our results indicated that a more negatively perceived after-hours e-mail tone influenced both vigour and fatigue via affective rumination.Further, our findings suggested diverging implications of after-hours e-mailing frequency and duration for problem-solving pondering, with longer duration and more frequent after-hours e-mailing co-varying with higher and lower levels of this form of rumination, respectively. These findings demonstrate the importance of considering various characteristics of after-hours e-mailing and corresponding implications of work-related rumination when studying employee well-being.
