This study aimed to develop a comprehensive research model to investigate the factors that impact the continuance intention to use remote work solutions. A new research model focusing on the mediating impacts of productivity and work flexibility was developed based on the TOE framework to explore how technological, organizational, and environmental factors influence the intention to use RWS post-pandemic era. Data were collected through a survey of 411 current RWS users in South Korea and analyzed using partial least squares structural equation modeling. The findings reveal that productivity and work flexibility exert significant mediating effects on the intention to continue using RWS. Furthermore, the roles of technological, organizational, and environmental factors are validated, except for the relationships between security and work flexibility, as well as management support and work flexibility. Finally, these results provide valuable insights and recommendations for RWS providers, user organizations, and government entities on meeting user needs and expanding the market size.
