Employee engagement has emerged as a critical factor in modern organizational success, particularly in the context of globalization, technological advancements, and evolving workforce expectations. Organizations today recognize that sustainable performance depends not only on financial resources but also on effective human capital management. Employees now seek meaningful work, recognition, and opportunities for growth, making it essential for organizations to create a supportive and engaging work environment that enhances both individual and organizational outcomes. The concept of employee engagement was first introduced by William A. Kahn, who described it as the integration of employees' physical, cognitive, and emotional energies into their work roles. Later, Wilmar Schaufeli expanded this idea by defining engagement as a positive and fulfilling state characterized by vigor, dedication, and absorption. These perspectives highlight that engaged employees are not only present at work but are also deeply involved and committed to their tasks. This study aims to examine the relationship between employee engagement and employee performance using a quantitative research approach. Data was collected through a structured questionnaire from 100 respondents across different organizational roles. The study analyzes key engagement factors such as motivation, communication, recognition, and work environment, and evaluates their impact on performance indicators like productivity, efficiency, and work quality. The findings of the study reveal a strong positive relationship between employee engagement and employee performance. Highly engaged employees demonstrate greater productivity, adaptability, and job satisfaction, while also contributing to organizational growth. The study concludes that organizations should prioritize engagement strategies such as effective communication, regular feedback, and recognition systems to enhance employee performance and achieve long-term success.
