Abstract.In an attempt to understand the reasons for employees' personal Internet use at work, known as cyberloafing, this paper attempts a new perspective to look at the phenomenon. As the barrier between the previously separate work and home domains reduces, employees are increasingly integrating their working and private world. This phenomenon has resulted in employees using their personal time for work-related tasks through technology in the privacy of their homes and private domain. Conversely, employees could be carrying out non-work related Internet use during office hours. This paper aims to explore the possibility of non-work domain as a factor for employees to cyberloaf. This paper proposed a conceptual model based on border theory and theory of interpersonal behaviour. The resultant augmented theory offers a richer explanation of how non-work domain affects employees' decision making process on cyberloafing.
