Informal learning networks can be valuable for L&D professionals to advance their careers, support work transitions, improve performance, and develop additional skills. ILNs are unstructured and voluntary communities of people interested in learning and growing through others within or beyond their organizations. These networks provide access to connections and expertise that may be unavailable in an organization's formal structures. The currency in an ILN is members' social and professional capital, rather than a mandate from management, a charter, or another externally imposed structure.
