This document discusses different types of corporate communication: horizontal, downward, and upward. Horizontal communication occurs between peers or coworkers and aims to coordinate functions, share information, solve problems, and resolve conflicts, but can be hindered by increased specialization, lack of recognition, suppression of differences, and ego clashes. Downward communication involves information flowing from top leadership down through managers to employees, allowing for organizational discipline, efficiency, and goal communication, but can lead to distortion, slowness, low morale, and lack of motivation. Upward communication comprises information moving from employees to managers and directors, enabling feedback but potentially facing issues with attitudes, skipping ranks, and organizational structure.
