The Four Layers of Diversity: A multidimensional approach to inclusive culture in the workplace

Antonio Topalović

In the context of globalization and an increasing demand for sustainable inclusive practices, understanding diversity in the workplace requires a multidimensional approach. This article presents and analyzes the Four Layers of Diversity model (Gardenswartz & Rowe, 2003), which encompasses four interrelated layers of identity: personality, internal, external, and organizational dimensions. Through critical engagement with existing diversity theories, the article emphasizes the importance of recognizing less visible dimensions of identity, such as personal experiences or organizational position. Research findings indicate that traditional approaches—focused primarily on visible characteristics—often overlook the complexity of identity, resulting in superficial organizational solutions. This article lays the foundation for developing strategies that promote equitable access to resources and participation, including inclusive hiring, onboarding processes, and the mitigation of unconscious bias. The Four Layers model is reaffirmed as a valuable framework for shaping inclusive organizational policies and practices. The article also highlights the need for continuous training of management and employees on diversity issues, as well as the integration of the model into everyday decision-making processes, thereby enhancing organizational resilience and contributing to long-term sustainability.
