Most of the workers in manufacturing industry, especially under assembly department have to perform their job in standing position due to the effectiveness. The research scope and objectives are to obtain the satisfaction of workers standing position to the workers. Besides that, the ergonomically design ergonomic working environment was implemented to reduce the aching feet, low back pain, swollen ankles and calves as well as leg and hip pain at the selected manufacturing plant. The data on the Musculoskeletal Disorders (MSDs) symptoms of pain and the workers’ risks of exposure to vibration were collected via questionnaire and Rapid Upper Limb Assessment (RULA). After implementing the ergonomic working environment, direct interview was conducted to get the feedback from the workers as well as to verify the working environment. The research found that the workers are having pain in the right heels and left heel with percentage 33.9% and 32.1% respectively. RULA result found that 50% of the workers score 3 or 4, about 29% score 5 or 6 and 21% score 7. Therefore, after implementing the ergonomic working environment, the percentage of painful body part was decreased, RULA score was reduced and muscle is not in fatigue. Most of the workers are satisfied, they felt happy and comfortable. Overall, it raised the awareness of ergonomic among the workers and the organization as well.
