This dissertation examines the impact of job satisfaction on organizational performance, using Tesco as a case study. It identifies issues related to job satisfaction among Tesco employees and how this affects organizational performance, including employee commitment, engagement, and turnover rates. The research aims to understand the concept of job satisfaction and organizational performance, identify key factors influencing both within Tesco, assess the association between them, and provide recommendations for improvement. The study employs a positivism philosophy, deductive approach, and descriptive research strategy, using quantitative data collected from 200 Tesco employees via a random sampling technique. Data analysis includes descriptive and inferential statistics, revealing insights into the influence of factors like working environment and co-worker relationships on job satisfaction and its subsequent impact on Tesco's overall performance. The findings support the hypothesis that job satisfaction significantly affects organizational performance, leading to recommendations for enhancing employee satisfaction to improve productivity and service quality at Tesco.
