Ergonomics plays an important role in work safety, Productivity, and employee well-being, specifically in the manufacturing sector, where workers are exposed to repetitive tasks, heavy lifting, and prolonged standing. The study scrutinizes how ergonomic interventions affect employee performance in the South African manufacturing industry, in relation to the Automotive Manufacturing plant. Case studies, data analysis, and interviews of the manufacturing firm in question will be explored. The study identifies key ergonomic challenges and their impact on productivity, absenteeism, and workplace injuries. Findings give insights that poor ergonomics contributes to musculoskeletal disorders, reduced efficiency, and high turnover rates, while effective ergonomic measures improve worker health, morale, and overall productivity. The study recommends industry-wide ergonomic policies, improved worker training, and technological interventions to improve working conditions.
