Abstract
With a focus on the Job Demands – Resources model (JD-R model), this paper examine the effect of the uncertain work environment (UWE) as an independent variable to explore the relationship between the job demands (JD) as moderating variable and job resources (JR) the mediator on employee job performance (JP). Commercial Banks of South Sudan employees were investigated through the distribution of 256 questionnaires, and 160 questionnaires were returned, which formed a response rate of 62.5%. The study hypothesized that; H1. The uncertain work environment has a negative influence on employee work performance, H2. Uncertain work environment affects job resources negatively , H3. Job resources have a positive impact on employee work performance , H4 . Job demands moderate the effect of job resources on work performance , H5 . Job demands moderate the influence of uncertain work environment on job resources and H6. Job demands moderate the impact of the uncertain work environment in work performance. Results confirm that (UWE) affect the (JP). They have a significant negative influence on (JP), (JR) has a substantial impact with (JP), (JD) had a significant negative influence on relationship between (UWE) and (JP)through (JR), and (JD) moderate the impact of (UWE) on (JR) positively.

Highlights
The success and the failure of any organization depend on how it maintains the working environment which is the most vital element (Journal, Management, & Global, 2002) in the productivity and job performance process, as an outcome of the employee engagement (Xanthopoulou, Bakker, Demerouti, & Schaufeli, 2007)
Based on the research findings, the study failed to reject the fifth research hypothesis (H5) and concluded that job demands moderate the influence of uncertain work environment on job resources
Job resources positively related to employee job performance, and the influence was significant
Summary
The success and the failure of any organization depend on how it maintains the working environment which is the most vital element (Journal, Management, & Global, 2002) in the productivity and job performance process, as an outcome of the employee engagement (Xanthopoulou, Bakker, Demerouti, & Schaufeli, 2007). This research paper is conducted to shed light on how uncertain work environment with the moderating of Job demands and mediating of Job Resources have a great impact on employee job performance in Banking Industry, especially in the post-war countries in South Sudan. Employee work engagement had been given a special focus for the last three decades to measure how much an individual contributes to her/his industry; according to studies, it is the main factor for job performance when employees are satisfied (Aziri, 2011). The researchers www.iiste.org reflect an uncertain work environment in addition to some constructs of both the job demands and job resources as variables to measure employees' job performance of commercial banks in South Sudan. Job demands moderate the effect of the uncertain work environment in job performance
