The purpose of this study is to investigate the impact of leadership and motivation on the job performance of new group leaders at Pama using work engagement as a moderating variable. A variety of literatures are utilised to describe the interactions between leadership style, work engagement, motivation, and job performance. This is a quantitative research approach, with the study object being a mining business and the unit of analysis being the group leader. Researchers employed the PLS-SEM technique and SMART-PLS software to analyse the data collected from the distribution of the formulary questionnaire. The findings of this investigation demonstrate that a number of hypotheses are validated while others are not. This study's management implication is to advocate the execution of a few supported hypotheses.
