It helps adolescents after transition to their first job to adapt rapidly to the new work and organizational situation. Positive social integration, especially a positive apprentice–trainer relationship and work group integration, helps the apprentices not only to overcome the uncertainties linked to this transition, but also to gain access to the resources needed for successful socialization and learning in the organization. The social integration develops within the first months in the new organization. First, we study how two indicators of social integration, namely the apprentice–trainer relationship and work group integration, develop over time. Second, we investigate how an individual’s reliability, the perceived person–occupation fit, and organizational resources predict the level and development of the social integration within the first months in the new job.enOrganizational entrySocial integrationSchool-to-work transitionApprenticeship370 - Erziehung, Schul- und Bildungswesen01A - Beitrag in wissenschaftlicher Zeitschrift1-18
