<![CDATA[Employee productivity is a central concern in resource-intensive industries where operational reliability depends on both human capability and disciplined work behavior. This study examines the associations of work ethic, job skills, and work motivation with employee productivity in an Indonesian mining company. A cross-sectional quantitative survey was conducted using a census of 50 employees at PT Pusaka Mineral Indonesia Sultra. Data were collected through a five-point Likert questionnaire and analyzed using descriptive statistics and multiple linear regression in SPSS 25. The results show positive and statistically significant associations between work ethic and productivity (B = 0.600, p = .005), job skills and productivity (B = 0.553, p = .009), and work motivation and productivity (B = 0.665, p < .001). The overall regression model was also statistically significant (p < .001). The study contributes by integrating normative, capability-based, and motivational employee resources within a single productivity model in a mining setting. The findings suggest that productivity interventions should combine ethical work norms, systematic skill development, and motivational practices rather than relying on technical training alone.]]>
