The Impact of Intrinsic Motivation on the Sustainable Extra-Role Performance with the Mediating Role of Job Engagement

Employee motivation and engagement are crucial in attaining optimum workplace productivity because when employees are driven and interested in their duties, they are more likely to give more of themselves, be more innovative, and actively contribute to the organization's success. The goal of this study is to examine the effects of intrinsic motivation and staff engagement on extra-role performance. It also examines how employee engagement functions as a mediating factor between these factors. The research participants are workers of a Kosovo-based energy production firm. The data were gathered using the convenience sample approach, with 350 people working in various jobs and locations. To investigate the study's hypotheses, we employed the PROCESS 4 macro model and multiple regression analysis. The study found that motivation from within improves job performance and has a positive relationship with work engagement. Similarly, when the influence of engagement on extra-role performance was investigated, the findings found that engagement had a very significant effect. Furthermore, there was evidence of a positive relationship between intrinsic motivation and extra-role performance, with work engagement serving as a moderator. This study makes an important contribution that sustainably motivated and engaged employees are essentially more likely to stay in the organization, reducing the cost of staff turnover. Good employee performance increases the organization's ability to adapt to change and innovate, contributing to long-term sustainability.
