The purpose of this study was to examine whether an individual's perception of career development influences job burnout. The career development dimension included career choice satisfaction, career satisfaction, and confidence of career future. As for the job burnout dimension, it consisted of exhaustion, cynicism, and professional efficacy. Survey data collected from 358 Taiwan flight attendants indicated that with the exception that career satisfaction did not show a significant effect on professional efficacy, career choice satisfaction and confidence of career future were significantly predictive of all three dimensions of job burnout. Implications of these findings and suggestions for future research are discussed.
