The results of the study show that in the study at CV Citra Gemilang, vertical and horizontal communication play a vital role. Vertical communication includes the distribution of information from upper management to the operational level and vice versa, ensuring the flow of information appropriately and efficiently through face-to-face meetings, WhatsApp, and email. Active efforts are made to overcome obstacles such as late reports by reprimanding and encouraging employee responsiveness. Vertical communication also emphasizes the ethics of formal communication with superiors. On the other hand, horizontal communication involves sharing information and collaboration between teams, especially in accounting. Challenges such as scheduling meetings and misunderstandings of messages are overcome through the use of electronic communication and open communication. Overall, vertical and horizontal communication at CV Citra Gemilang creates an inclusive, collaborative, and productive work environment]]>
