Etiquette refers to social norms and expectations for behavior within a society or group. Business etiquette differs from social etiquette in that it focuses on hierarchy and professionalism rather than courtesy. Good business etiquette includes practices like proper email communication, introductions, dining etiquette, telephone etiquette, appropriate office and cubicle behavior, meeting etiquette, business card exchange, dress code, and networking. Mastering business etiquette helps one appear more polished, professional, and confident in work settings.
