What term refers to the display of manners and professionalism in business settings?

The term that encompasses the display of manners and professionalism in business settings is business etiquette. This concept includes the expectations for how individuals should conduct themselves in a professional environment, including principles of proper behavior, communication, and interactions with colleagues and clients. Business etiquette helps to foster positive relationships and create a respectful workplace culture.

While other terms like business conduct and corporate behavior relate to guidelines for operation and expectations in a business environment, they do not specifically focus on the social niceties and manners that define how professionals interact. Business ethics refers to the moral principles that govern a person's or group's behavior, which encompasses a broader lens than merely manners and professionalism. Thus, business etiquette is the most accurate term for describing the essential social conduct expected in business settings.
