As more and more organizations provide employees access to the Web, the level of abuse is on the rise. Structured equation modeling was used to examine the antecedent and perceptual factors impacting accessing work-related Web sites and personal-related Web sites in the work environment. The results indicate that management support, experience and perceived ethical beliefs have a significant negative influence, while self-training and perceived enjoyment had a positive influence on personal-related Web access. Internet experience, formal training, and all the perceptual factors influenced work-related Web site access. The findings of the study contribute to an expanding understanding of the factors promoting Web usage and have important implications for the management of information systems.
