Suffering office insult
Don’t take offence at an insult. Hide your anger for it suggests that you take the insulter too seriously. Don’t react defensively. Take a moment to collect your thoughts and stand your ground. Maintain eye contact with the colleague, smile if you can manage it. Diffuse the situation by shifting subject or making some conversational small talk. Bring your colleague back to the main subject and remind him of common (your) goals. Watch out for your intonation and facial expression when talking. Don’t discuss the situation with your boss, avoid being labeled as „whiner” or „complainer”.
