Etiquette refers to the common rules that govern good social behavior and interactions. These social etiquettes are important in both personal and professional settings. Some key social etiquettes include using good manners, being punctual, following appropriate dress codes, greeting people, making eye contact and giving firm handshakes. In the digital age, good social media etiquette involves being polite in online communications, limiting mass emails and texts, avoiding unprofessional abbreviations and emojis, and respecting others' privacy by not posting private content without permission. Social etiquettes reflect cultural norms and help promote smooth social and business interactions.
