The present longitudinal field study investigated the antecedents and consequences of an actual career change. The framework for this study was Rhodes and Doering's (1983) model of career change. We examined the effect of individual and organisational characteristics on career change behaviour. The individual characteristics were: traits (Openness to Experience, Extraversion, Conscientiousness and general self-efficacy), demographic factors (age, gender, marital status, and children), human capital (education level and occupational tenure), job satisfaction, job search activity and intentions to leave; and organisational factors (job security and salary). The findings showed that a range of individual characteristics were associated with career change including, Openness to Experience, Extraversion, gender, age, educational level, and occupation tenure. However, job security was the only organisational factor related to career change. One year after career change, individuals reported higher job satisfaction, improved job security and a reduction in the number of hours worked. (Contains 4 tables.)
