Information and communication technology (ICT) tools have become an integral component of our lives, enabling individuals to seamlessly cross the work/life border with minimal effort. This paper examines the mechanisms through which work‐related ICT use beyond worktime (Wk_ICT) impacts work–life balance (WLB) through four mediator paths: work‐to‐life conflict, life‐to‐work conflict, work‐to‐life enrichment, and life‐to‐work enrichment. Data from 423 professionals from Canada was analyzed using the multiple mediation approach with bootstrapping using the PROCESS add‐on to SPSS. The results allude to a possible downward spiralling effect of diminishing WLB resulting from excessive work ICT use beyond worktime. The findings add to the literature by empirically demonstrating the mechanisms by which Wk_ICT impact WLB through cross‐domain conflict and enrichment.
