(THE) IMPACT OF DIVERSITY ON CIVIL AVIATION CASE STUDY OF SRI LANKA CIVIL AVIATION

다국어 초록 (Multilingual Abstract)

This study investigates the impact of workforce diversity on organizational performance within Sri Lanka’s civil aviation sector, with a particular focus on the mediating roles of employee engagement and employee commitment. Workforce diversity has become an essential organizational priority as aviation industries worldwide adapt to increasing globalization, technological advancement, and evolving service expectations. In this context, the study explores how differences in employees’ backgrounds, experiences, and perspectives influence organizational culture, shape employee attitudes, and contribute to overall performance outcomes within a highly regulated and competitive environment.
A quantitative research approach was adopted, and data were collected through structured questionnaires administered to employees representing various hierarchical levels, including managerial, operational, and administrative roles. This diverse sample allowed the study to capture a wide range of insights reflective of the sector’s evolving workforce composition. Structural Equation Modeling (SEM) was employed to analyze the collected data and to test the hypothesized relationships among workforce diversity, employee engagement, employee commitment, and organizational performance. SEM enabled an examination of both direct and indirect pathways, offering a comprehensive understanding of how diversity-related factors interact within organizational settings.
The findings indicate that workforce diversity exerts a significant positive effect on organizational performance. Diversity enhances performance directly by enriching problem-solving capabilities, broadening the pool of ideas, and promoting creative decision-making. Indirectly, diversity strengthens performance through its influence on employee engagement and commitment. When employees perceive their workplace as inclusive and respectful of individual differences, they demonstrate higher levels of motivation, emotional investment, and willingness to contribute to organizational goals. These outcomes highlight the strategic value of cultivating an inclusive workforce that leverages diversity as a source of competitive advantage.
This study contributes to the growing body of literature on diversity management by offering empirical evidence from Sri Lanka’s civil aviation industry, a sector where academic research on diversity remains limited. The results provide meaningful implications for policymakers, regulatory authorities, and aviation management practitioners seeking to enhance inclusivity, organizational effectiveness, and long-term sustainability. By emphasizing the importance of workforce diversity, the study underscores the need for aviation organizations to institutionalize inclusive practices, develop supportive leadership approaches, and foster a culture that fully harnesses the benefits of diverse human capital.
