The data were then analyzed descriptively and using regression and correlation for inferential statistics. Results of the study showed that leadership and work motivation either individually or collectively have a positive and significant impact on the performance of employees of PT. Great Mining. These findings show that the more effective the leadership is and the higher the work motivation is, the better the employees’ performance will be; whereas the less effective the leadership and the lower the work motivation is, the worse the employees’ performance is.
