Tehran Business Pulse

Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
Lunch Break 1:00 PM - 2:00 PM.
Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.

Zurich Business Pulse

Culture Precise, formal, and highly efficient. Values quality and punctuality above all.
Lunch Break 12:00 PM - 1:00 PM.
Pro Tip The ideal window is 9:00 AM to 11:30 AM. Punctuality in Switzerland is non-negotiable; being even one minute late is considered a serious lack of professionalism. Keep your discussion focused, data-driven, and highly organized. Avoid calling during the 12-1 PM lunch hour.
