Due to population aging and its implications for organizations and societies, organizational practices for older workers (OPOWs) play a relevant role in multiple research disciplines. So far, most reviews on this topic operationalize organizational practices as antecedents of older workers’ outcomes. We extend this perspective by illustrating multilevel antecedents and outcomes of OPOWs. In doing so, we demonstrate how these organizational practices directly and indirectly affect older workers, organizations, and society and how, in turn, older workers, organizations and society impact OPOWs. Drawing on a literature review, we discuss key theories and present current empirical findings from multiple research disciplines to propose an integrated cross-disciplinary model with the potential to guide future research and practice.
