Abstract

With the fantastic features of smartphones, smartphone addiction is a prevalent phenomenon. However, there is a lack of theory-based understanding of how smartphone addiction affects employees’ personal and work lives. The purpose of this study is to investigate the role of smartphone addiction in reinforcing techno exhaustion and life invasion and the final effects of these factors on job performance, and this study applied stress–strain-outcome (SSO) as the foundation of the model. In total, 475 responses were obtained from office and service workers in Iran by a survey. Our findings show that smartphone addiction leads to enhancement in job performance, whereas it significantly strengthens life invasion and techno exhaustion, and thereby life invasion and techno exhaustion dramatically reduce job performance. Our findings indicate the two-sided role of direct and indirect effects of smartphone addiction. Implications for both organizations and employees are discussed. • Stressor-strain-outcome framework is utilized to examine smartphone addiction. • Smartphone addiction leads to enhancement in job performance. • Smartphone addiction significantly strengthens life invasion and techno exhaustion. • Life invasion and techno exhaustion dramatically reduce job performance. • The negative indirect effects of smartphone addiction are more powerful than its positive direct influence.
