Supervisor phubbing (or phone snubbing) is the phenomenon where a supervisor snubs a subordinate by favoring his/her mobile phone above him/her when they are in a meeting. Subordinates who are phone snubbed by supervisors often feel neglected and turn to their own phones and virtual social circles for acceptance. The study aims to explore the impact of Supervisor Phubbing (SP) on Cyberloafing (CL), taking Workplace Ostracism (WO) as a mediator and Psychological Detachment (PD) as a moderator. Social Exchange Theory (SET) and Expectancy Violations Theory (EVT) are put forward as the underpinning theories to explain the underlying mechanism in the proposed relationships. Utilizing the time lagged method, data was collected from 267 employees working in varied industries in India. Statistical tools such as SPSS 21, AMOS 21, and PROCESS, were utilized to test the hypothesised model. The findings show that SP causes subordinates to feel ostracized which in turn, leads to CL. The study also examined how PD can act as a moderator and create an impeding effect on CL, WO, and PD emerged as significant mediator and moderator respectively. It is pertinent for organizations to understand that unfriendly practices such as SP can lead to organizational repercussions like WO and CL. Discussion on implications followed by limitations and future scope of research is included in the paper.
