Despite widespread recognition that human resource management (HRM) practices drive organizational outcome, it remains unclear whether HR inputs affect organizational productivity in the public service delivery. Using the Social Exchange Theory and Resource Based View (RBV), this study develops and tests a dual path structural model examining the influence of four HRM dimensions-Recruiting and Selecting, Working Conditions Training & Development, and Job Supervision- on organizational Productivity, alongside the mediating role of Employee Work Attitude, Adopting primary data from N=330 public sector employees across local government district assemblies, the conceptual framework was empirically validated using Partial Least Square Structural Equation Modeling (PLS-SEM) via SmartPLS. The empirical findings reveal that all the four HRM practices exert statistically significant positive direct effects on organizational productivity, with training and development (?=0.242 p<0.001) and Working Conditions (?=0.215 p<0.001) emerging as the strongest structural drivers. Furthermore, Employee Work Attitude stood out as the single most potent predictor of organizational productivity (?=0.2=345, p<0.001) and was confirm to act as a statistically significant partial mediator (?=0.201 p<0.001) bridging HRM inputs and performance outputs. Overall, the structural model demonstrated substantial explanatory power, accounting for 56.4% of the total variance (R2=0.546) in Organizational Productivity and 42.8% of the total variance (R2=0.428) in Employee Work Attitude. These results demonstrated that HRM interventions function as a synergistic system enhancing technical operational capabilities while simultaneously fostering positive employee attitude rooted in organizational reciprocity. The study offers vital theoretical contributions to public administration literature and provides actionable policy recommendations for public sector leaders seeking to curb workplace disengagement and optimize service delivery.
