Mentoring is increasingly viewed as a set of developmental relationships embedded in everyday work life, emphasizing informal, trust-based interactions that support performance, learning, and career progression. The field has shifted from a sole focus on dyadic mentor–protege relationships to developmental networks that weave together multiple ties, including peers, across formal and informal settings, guided by social network perspectives to illuminate career development within organizations. Methodologies favor network-informed designs and contextual analyses that examine how various mentoring functions operate within work contexts.
