Chicago Business Pulse
- Culture Practical, hardworking, and friendly. A major hub for logistics, finance, and manufacturing.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best times for calls are 9:00 AM to 11:30 AM. Chicagoans are known for being practical and direct but also friendlier than their East Coast counterparts. The Central Time Zone is the "Goldilocks zone" for North American business, allowing for easy syncs with both NYC and LA.
Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
