- Lunch Break 1:00 PM - 2:00 PM.
- Pro Tip Best call window is 10:00 AM to 12:00 PM. Sri Lankans value education and professional titles. Business culture is relational; spend time on polite introductions. Punctuality is appreciated. Be aware of potential power disruptions and have a backup communication plan like WhatsApp.
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.
