This research paper aims to investigate the concept of technologically driven Cognitive Intrusion of Work (CIW) on family life and vice versa. Due to the current situation, people’s work-life balance is impacted by continuous usage of technology for work and personal purposes and is referred to as “technoference”. The primary motivation of this research is to establish the reliability and validity of the constructs, namely, work interference with personal life (WIPL); personal life interference with work (PLIW), and work personal life enhancement (WPLE) on work-life balance to study their link with work-life balance. To assess the uni- dimensionality of the scales, both exploratory and confirmatory factor analyses along with scale reliability and validity were performed. The research method- ology was a cross-sectional design, and respondents were 641 higher education teachers. The findings established a good relationship between the three constructs and work-life balance, indicating that technologically driven cognitive intrusion of work impacts personal life and vice versa, i.e., cognitive intrusion of personal life happens at work impacting the work-life balance of individuals. The findings help to conclude that people are impacted by cognitive intrusion due to technol- ogy’s continuous influence in our day-to-day lives. The study is directly linked to contemporary organizations as they have increased their technology usage during work-from-home in the current pandemic times.

A host of pertinent research work is available from different parts of the world as work-life balance is related to all individuals worldwide [1–6]. Some profound literature suggests the transition of work-life balance to work-life integration as boundaries between work © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021 A.
