The rapid diffusion of digital communication technologies into Nigerian workplaces, accelerated by the COVID-19 pandemic and the subsequent normalisation of telework, has produced a communication environment in which employees are almost continuously reachable through email, instant messaging, video conferencing, and enterprise collaboration platforms. This study offers a critical appraisal of the existing literature on digital communication, information overload, and telework stress in the Nigerian context, examining the extent and nature of digital communication dependence in Nigerian telework arrangements, the causes and manifestations of information overload and technostress among Nigerian teleworkers, and the adequacy of existing coping strategies and organisational responses. This study was anchored on Technostress Theory. The study adopted a qualitative critical/systematic literature review design. The appraisal found that Nigerian teleworkers report significant positive relationships between telework intensity and stress, that information overload independently predicts negative communicative and cognitive outcomes among Nigerian digital users, and that the technostress dimensions identified in international scholarship (techno-overload, techno-invasion, techno-complexity, techno-insecurity, and techno-uncertainty) are conceptually present but empirically underexplored in Nigerian organisational research, which remains dominated by general occupational stress framing rather than technology-specific diagnostic constructs. The researcher concludes that Nigerian telework and digital communication research lacks a locally validated technostress measurement framework and organisationally embedded mitigation strategy, and proposes a research and policy agenda for addressing this gap.
