Organizations attempt to mitigate nonwork-related behaviors of employees to maintain productivity and employee engagement. As a manifestation of nonwork-related mobile computing, mobile loafing is considered subject to control by organizations. According to Akers’ social learning theory, deviant behaviors are usually learned through imitating others or through experience. In addition, new information on deviant behaviors can influence the mechanisms of conducting those behaviors. This study investigates how perceptions of mobile-loafing are moderated by phase-shifting perception after organizations’ announcements of formal control. In particular, we hypothesize that phase-shifting perception has moderating effects on employees’ perceptions of mobile-loafing, such as neutralization and peer loafing, from time 1 to time 2. The results of this study will contribute to information systems (IS) research by suggesting the moderating role of phase-shifting perception in the context of mobile-loafing.
