Abstract
This study aims to analyze the influence of horizontal communication, vertical communication, and diagonal communication on employee morale at the Rantau Utara District Office. The study used a quantitative approach with a survey method. The study population consisted of 33 employees, all of whom were sampled through a saturated sampling technique. Data were collected using a questionnaire and analyzed using validity tests, reliability tests, classical assumption tests, multiple linear regression, partial tests, simultaneous tests, and coefficients of determination using SPSS 27. The results showed that horizontal communication, vertical communication, and diagonal communication each had a positive and significant effect on employee morale. Simultaneously, the three variables also had a significant effect on morale. Vertical communication was the variable that had the greatest influence compared to the other two variables. The Adjusted R Square value of 0.840 indicated that 84% of the variation in morale could be explained by the three forms of organizational communication, while 16% was influenced by other factors outside the research model. These findings confirm that effective organizational communication plays an important role in increasing employee morale and supporting the creation of more optimal public service performance.
