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 encompasses written, verbal, visual, and electronic communication and means behaving respectfully towards all, adhering to the company's code of conduct, being mindful of time and resources, and dressing appropriately. Intercultural communication acknowledges differences in values and behaviors between cultures to find common ground and universal understanding.
