The Role of Performance Appraisal and Work–Life Balance on Work Engagement: The Mediating Effect of Job Security in Malaysia’s Oil and Gas Industry

This study investigates the relationship between performance appraisal and work–life balance with the level of work engagement among employees in the oil and gas industry in Malaysia, using job security to as a mediating variable. The study is based on Social Exchange Theory (SET), which suggests that employees will return positive responses to positive actions from their organisation, including greater employee engagement in return for treatment with fairness in appraisal systems and work–life practices. A quantitative approach with cross sectional research design was used and structured questionnaire was administered to the employees of one of the big oil and gas organisations in Malaysia. A total of 236 usable responses were obtained and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) in the program of SmartPLS 4. The research framework includes direct relationship between the performance appraisal and work engagement and between work–life balance and work engagement, and the mediation role of job security in the above relationships. The results showed that performance appraisal and work–life balance had significant impacts on work engagement, with job security having the highest positive impact on engagement. The results of mediation analysis also showed that job security plays a significant role in mediating the relationships between HR practices and employee engagement. They found that such practices were interpreted as signals of stability and support at the organisation, from which employees responded with emotional, cognitive and physical investment. These results support the theory of Social Exchange Theory (SET), which states that HR practices are seen as 'signals' for stability and support in the organisation, which employees interpret and reciprocate through emotional, cognitive and physical investment. In practice, the study points to the need for clear evaluation systems, supportive working–life policies and communication about job security to help maintain engagement in a turbulent industrial landscape. The study adds to the theoretical and practical knowledge of the mechanism of employee engagement in high-risk sectors.
