Peer mentoring can offer employees a valuable source of support and information in the workplace.[43] Peer mentoring offers a low cost way to train new employees or to upgrade the skills of less experienced workers.[44] Mentees may feel more comfortable learning from a peer than in a hierarchical setting.[45] Mentors as well as mentees may also benefit from the bonds they form with colleagues.[46] In 1978 Edgar Schein described multiple roles for successful mentors in the work setting.[47] New employees who are paired with a mentor are twice as likely to remain in their job than those who do not receive mentorship.[48][49]
