The problem of vacant jobs—driven by chronic labor shortages—is intensifying in particular among manufacturing-based small and medium-sized enterprises, and welding, despite being a core task in the production process, is a field in which attracting and retaining new workers is not easy. A survey of newly employed workers and company representatives in the welding field of the root (ppuri) industries—the foundation of manufacturing, encompassing casting, die and mold making, welding, and surface treatment—found that new workers regard “experiences of competence development and growth,” alongside “improved working conditions,” as important factors for staying in their jobs. The main difficulty new workers experience was identified as “difficulty learning from senior colleagues or supervisors.” The barriers to participating in education and training, meanwhile, were “a mismatch between training and the worksite” and “a lack of time,” and workers expressed a preference for “worksite-based (simulation)” training and “mentoring”-based support. On this basis, the brief presents policy tasks that link new workers’ job settlement with job-skills development.
