People are the building blocks of every organization. The employees are on their optimal job performances if they are in an affective-motivational state of mind, which is known as work engagement. This descriptive-correlation study, involving 105 employees of the University of the Immaculate Conception (UIC), aimed to describe their levels of work engagement, motivational potentials of certain job characteristics and performance. It also assessed how strongly work engagement and motivational potential of certain job characteristics relate to performance of the employees. Moreover, this investigation determined which one among these variables, namely, work engagement and motivational potential significantly influences employee performance. A 17-item questionnaire on Work and Well-being Survey by Schaufeli and Bakker (2003) was used to determine the level of work engagement. Job Diagnostic Survey Questionnaire by Hackman and Oldham (198) was used to measure the motivational potential of certain job characteristics. The performance evaluation result was used to describe performance level of personnel. Data was treated using mean, Pearson Product Moment Correlation, Multiple Regression. Findings revealed that work engagement of the employees is very high, motivational potential is high, and specifically, for the Support Service Personnel, both work engagement and motivational potentials are significant predictors of performance.
