The coefficient of determination (R²) value is 0.469, indicating that the percentage of the influence of internal communication on employee work effectiveness was 46.9%. while the remaining of 53.1% was influenced by other variables outside this study, such as the work environment, work discipline, compensation, and organizational management policies and practices.]]>
