This study seeks to provide a comprehensive understanding of emotional intelligence by reflecting on its conceptual framework, analysing the theoretical foundations that support it and evaluating its relevance in relation to job performance in workplace settings. Through this investigation, the study aims to enhance the current comprehension of emotional intelligence, shedding light on its theoretical basis and practical implications for enhancing performance in professional environments. By pursuing these aims, the study endeavours to offer valuable contributions to the field, advancing understanding of emotional intelligence and its impact on achieving success within organisational contexts. The study examines three prominent models of emotional intelligence. The first model, developed by Salovey and Mayer, establishes a foundational framework for understanding emotional intelligence as a multifaceted concept. This model outlines essential components integral to emotional intelligence, offering valuable insights into the core abilities within this domain. The Bar-On model of emotional intelligence, proposed by Reuven Bar-On, offers a comprehensive framework that emphasises the role of emotional and social factors in overall well-being and success. Bar-On's model encompasses various facets, including intrapersonal, interpersonal, adaptability, stress management, and general mood. On the other hand, Daniel Goleman's model of emotional intelligence, popularised by the author Daniel Goleman, highlights the significance of emotional competencies in personal and professional success. Goleman's model revolves around five key components: self-awareness, self-regulation, motivation, empathy, and social skills. The paper provides the affirmative link between emotional intelligence (EI) and diverse aspects of job performance, accentuating the significance of organisations' acknowledging and nurturing the emotional competencies of their employees. Amidst the ongoing evolution of workplaces, the strategic incorporation of EI emerges as a pivotal strategy for fostering employee well-being and securing organisational prosperity
