Given the wide range of mobile and communication devices in everyday life and the day-to-day work of most individuals, people often become dependent on their smartphones - this dependency creates a modern phobia. The discomfort or anxiety caused by being unable to use a smartphone is referred to as “Nomophobia.” This paper outlines our approach to survey the impact of supportive leadership and co-worker support on nomophobia, in terms of the role of affective commitment and human resource management (HRM) practices. This study employs structural equation modelling (SEM) based on data obtained from a questionnaire into organizations, with a view to revealing comprehensive findings concerning nomophobia. Additionally, some measures to control nomophobia will be suggested.
