Effective and ethical business communication is essential for transmitting information internally and externally in a way that follows ethical standards and does not insult or make others uncomfortable. It requires messages to be efficient, clear, and honest. Professionalism in the workplace involves behaving respectfully through written, verbal, visual, and electronic communication by respecting others, being honest, adhering to company policies, and dressing appropriately. Intercultural communication acknowledges cultural differences to find common ground and universal understanding.
