Horizontal communication does come with some disadvantages. Management may have a greater problem maintaining control as horizontal communication increases. This is, in part, because management can derive much control and power if it controls the flow of information. Horizontal communication can also create conflict between employees exposed to each other through the communication process. It is also more time-consuming if vertical communication is required to ratify decisions made during horizontal communication or to confirm information received through horizontal communication. Finally, it may create a lack of discipline if strict procedural rules of communications are not imposed and followed.
