Which of the following should always be avoided in professional communication?

Employing jargon in professional communication should always be avoided, as it can create barriers to understanding. Jargon refers to specialized terminology used by a particular group or profession that may not be familiar to others outside that field. When communicating in a professional setting, it is crucial to ensure that the message is accessible to all intended recipients. Using clear and straightforward language fosters better understanding and enhances collaboration, as everyone can follow the conversation without confusion.

In contrast, clear language, conciseness, and politeness are essential elements of effective communication. Clear language helps convey ideas without ambiguity. Being concise ensures that the message is direct and to the point, respecting the recipient's time. Staying polite creates a respectful communication environment, which is vital for maintaining professional relationships and effective teamwork.
