Workplaces today grant precedence to employee well-being and organizational commitment because they advance sustainable organizational performance. The study analyzes emotional intelligence (EI) as a mediator that connects employee well-being to organizational commitment. A mixed-methods research design collected quantitative data from 300 workers from multiple businesses using validated instruments designed to measure EI and well-being as well as commitment. Information from this research originates from 25 participant interviews through semi-structured sessions. The study demonstrated emotional intelligence serves as a substantial mediator that connects employee well-being and organizational commitment levels (β = 0.52, p < 0.001), yet affective commitment displays the most significant correlation. Employees possessing high EI effectively handle stressors, which produces stronger organizational loyalty through resilient behaviors. Professional implementation should include EI development training coupled with well-being enhancement strategies to boost organizational commitment. EI functions as an essential psychological tool that creates connections between individual welfare and organizational cohesion.
