An Assessment of the Effect of Workforce Diversity on Organizational Culture of Public Institutions in Zambia: A Case Study of the Ministry of Foreign Affairs and International Co-Operation

This study assessed workforce diversity and its effect on organizational culture at the Ministry of Foreign Affairs and International Co-operation in Lusaka. The specific objectives were: to identify the existing workforce diversity traits at the Ministry of Foreign Affairs and International Co-operation in Lusaka; to determine the relationship between workforce diversity and organizational culture practices in Lusaka, and to examine the effect of workforce diversity on organisational culture in public institutions through the Ministry of Foreign Affairs and International Co-operation in Lusaka. Employing a mixed-method design, the research involved a sample of 50 respondents for a quantitative aspect while saturation method was for a qualitative design. Questionnaires were used for quantitative data while interviews were used for qualitative data. Purposive and random sampling techniques were used as sampling techniques. Quantitative data were analyzed using descriptive statistics, and qualitative responses were thematically analyzed to capture comprehensive insights. The findings reveal that the ministry’s workforce is diverse in terms of gender, age, educational qualifications, and management levels. Quantitative results indicate that 70% of respondents are male, with the predominant age group being 41-50- years (40%), and 44% of the staff holding a graduate degree. Qualitative feedback further indicates that this diversity contributes positively to creativity, innovation and problem-solving within the organization. However, some challenges were identified, including communication gaps and inconsistencies in managing diverse teams, which could hinder the full potential of a diverse workforce in terms of performance and productivity. The study concludes that (1) the ministry exhibits significant workforce diversity that requires systematic monitoring;(2) there is a positive relationship between workforce diversity and effective organizational culture practices; and (3) well-managed diversity enhances overall organizational performance. Based on these conclusions, it is recommended that the ministry establishes a centralized system for monitoring diversity metrics, implement regular diversity training and team-building initiatives to foster inclusivity, and develop robust diversity management policies to ensure equitable treatment and leverage diverse perspectives.
