This paper investigates environmental factors affecting employee health and performance in workplace environments. These factors are divided into two categories: environmental factors, including temperature, humidity, ventilation, lighting, and noise, which impact physical and mental comfort, and managerial and organizational factors, such as work organization, employee rotation, training, workspace design, and ergonomic practices, which ensure physical comfort during tasks.Using interviews, direct observations, and case studies, the study explores how these factors influence employee well-being and productivity. The findings reveal that an optimal work environment characterized by moderate temperature, adequate lighting, effective organization, and ergonomic practices significantly reduce health risks, such as fatigue and musculoskeletal pain, while enhancing productivity and focus. This paper concludes that a well-organized workplace, addressing both environmental and managerial factors, is essential for improving employee well-being and performance.
