Abstract

Employee performance remains a central concern in public security institutions because the effectiveness of law enforcement depends largely on how well officers execute their assigned duties. Job responsibility forms a key component of work design since clearly defined roles and accountability structures shape employee behavior and productivity. This study aimed to examine the moderating effect of organizational support on the relationship between job responsibilities and employee performance in the NPS. The research was anchored on Conservation of Resources (COR). An explanatory research design was employed, targeting 2000 respondents, with 333 selected through multistage sampling based on Slovin’s formula. Data were collected using a structured questionnaire and analyzed using descriptive statistics such as frequencies, percentages, means, and standard deviations. Inferential statistical tests, including regression and correlation, were conducted to establish the relationships among study variables, with hypotheses tested using multiple regression and hierarchical regression for moderation. The findings showed that employees reported relatively high levels of performance and job responsibility, while perceptions of organizational support were moderate. Correlation results indicated significant positive relationships between job responsibility and employee performance (r = 0.691, p < 0.01) and between organizational support and employee performance (r = 0.758, p < 0.01). Regression analysis further established that job responsibility had a positive and significant effect on employee performance (β = 0.083, p < 0.05). Moderation analysis revealed that organizational support significantly strengthened the relationship between job responsibility and employee performance (β = 0.214, p < 0.05). The study concludes that supportive organizational environments improve how employees respond to work responsibilities and contribute to better performance outcomes. The findings suggest that management in the National Police Service should strengthen role clarity, accountability mechanisms, and structured task allocation systems to improve officer effectiveness. The study also recommends further research on additional organizational factors that may influence performance in policing institutions.
