Job-hopping is the practice of making frequent voluntary job changes. Integrating theory and research from career and organizational turnover research, two distinct motives for job-hopping were proposed. The escape motive describes frequently changing jobs to escape disliked work environments, whereas the advancement motive describes frequently changing jobs as a means of career advancement. A self-report measure of job-hopping motives was developed and validated using responses from 221 students and 1,528 adults. Factor analysis showed that the motives are distinct but moderately related. The escape motive was associated with negative reactivity (impulsivity, negative affect) and script-based turnover decisions. The advancement motive was associated with positive proactivity (persistence, growth need strength), and protean, boundaryless, and kaleidoscope career theory components. Both motives were associated with organizational withdrawal, quick turnover decisions, and increased turnover. Job-hopping motives predicted historic job change rate over and above demographic, career, and organizational turnover variables.
