Abstract: This research examines the effect of employee engagement programs at Tenneco Clean Air India Pvt. Ltd. with a focus on the role played by the HR Manager in generating commitment and productivity among the employees. Applying a descriptive research design, information was gathered using standard questionnaires from 118 employees in Chennai. The findings showed that successful engagement strategies have a strong positive effect on employee morale, loyalty, and job satisfaction. But it is in recognition and internal communication that there are still challenges. The research indicates the necessity of regular appreciation initiatives, open feedback systems, and improved wellness programs to fill these gaps. The research indicates that positive HR practices can be linked to better employee retention, job performance, and overall organizational success. This study provides useful information for HR professionals seeking to improve engagement and develop a more productive and motivated workforce.
