This study was completed to understand whether or not work addiction or work addiction intensity could be predicted from mobile technology use. The study further investigated whether or not gender, workspace, income, or education level would moderate the relationship. The sample used was drawn from service industry employees who are not in the information technology service. The participants were over 18 years old, worked full-time, and used mobile technology to access email. A standard multiple regression showed that mobile technology was a statistically significant predictor of work addiction but not work addiction intensity. It further showed that none of the moderating variables were statistically significant. The findings resulted in more areas of research that need to be done; some of which are investigating the way work is done, the type of compensation received, and whether specific income levels or business types are more prone to attract or help create work addicts.
