As organizations increasingly embrace Internet technologies in daily work activities, an unintended consequence is the growing personal Internet use by employees. This study examines the association between job characteristics and a particular form of personal Internet use at work, personal online communication (POC). The study analyzes data of the 2008 Networked Workers Survey sponsored by the Pew Internet & American Life Project. The results demonstrate that job characteristics explain a large, significant portion of the variance of POC at work. The findings suggest that for jobs with high knowledge intensity, managing POC could be approached from a work–life balance perspective. The study also suggests that changes in work structure, job variety, and autonomy could have significant implications for managing POC activities in the wired workplace.
