In some cases, a mentor will experience changing responsibilities and commitments that make it impossible to devote sufficient time to his or her mentee. In some cases, mentors and mentees will not be compatible. Any mentor or mentee should be free to send a request to his or her chair or (in non-departmentalized schools) dean to dissolve the mentoring relationship and identify another mentor for the new faculty member. In such cases, neither mentors nor mentees should feel that they have failed. Mentoring relationships require time and rely on personal compatibility and will not always be successful. When they are not, it’s best to make a change, and neither party is to blame.
