Abstract

This study investigates the effects of organizational culture on employee performance in Zanzibar's public hospitals, with a specific focus on the moderating role of socio-demographic characteristics. Guided by Denison’s Organizational Culture Theory, the study evaluates three key dimensions of culture involvement, consistency, and adaptability as core constructs influencing employee performance. A cross-sectional descriptive design employing quantitative methods was used. Data were collected from a randomly selected sample of 288 healthcare workers, drawn from a population of 592 employees with at least three months of tenure in selected public hospitals across Zanzibar. Data analysis was conducted using multiple linear regression via IBM SPSS Version 25. The findings reveal that all three cultural dimensions significantly contribute to employee performance, with involvement emerging as the strongest predictor. Moderation analysis highlights gender as a significant socio-demographic moderator in the relationship between organizational culture and employee performance. The study recommends enhancing employee involvement through participatory decision-making mechanisms. To strengthen consistency, internal systems and standardized procedures should be reinforced. To improve adaptability, staff development programs and innovation incentives are encouraged. Additionally, the study calls for further research into other potential moderating factors and advocates for longitudinal designs to gain a deeper and more dynamic understanding of these relationships over time. Keywords: Organizational Culture, Employee Performance, Healthcare, Involvement, Adaptability, Consistency, Moderation Analysis.
