"Constant connectivity" is a phenomenon brought about by our interconnected world. However, it is not just a multidisciplinary field investigated by researchers from the IS field, organization studies, management studies and psy-chology, but also an actual challenge which knowledge workers face every day. This literature review provides a thematic but also methodological overview of this still young research field on three levels: (1) the paradigm funnel, (2) units of analysis (individual, organizational, societal) and (3) four different thematic streams in the literature. On the basis of the lacks discovered in the paradigm funnel, omitting society as unit of analysis, and thematic gaps in the existing literature, an avenue for future research is developed. Furthermore, as "constant connectivity" and, virtual communication, respectively became a success factor for companies, I reveal important managerial implications for practitioners derived from my thematic analysis.
