This study examines the association between negative mentoring experiences and protege intentions to leave the mentoring relationship. The role of perceived mentoring alternatives and fear of mentor retaliation was also examined as moderators of the relationship between negative mentoring experiences and intentions to leave. Results indicate that several types of negative mentoring experiences predict intentions to leave the mentoring relationship. In addition, three moderation effects were found. The results are discussed in terms of enhancing our understanding of mentoring relationships in the workplace. (Contains 3 figures and 2 tables.)
