The main purpose of this guide is to provide some ideas for employers of apprentices to provide an environment in which strong informal bases of support can succeed. Formal mentoring is an important aspect of apprenticeships; however, it is also informal mentoring--practices that are difficult to formally nurture--that plays a significant and effective role in supporting the overall well-being of an apprentice. This good practice guide is designed to help employers think about and provide work-based social support structures that may contribute to the health and well-being of young apprentices as they transition to the world of work. [This good practice guide is based on the report "Beyond Mentoring: Social Structures of Support for Young Australian Carpentry Apprentices" by John Buchanan, Catherine Raffaele, Nick Glozier and Aran Kanagaratnam from the University of Sydney. For that report, see ED567792.]
