Synchronization Context
Syncing between London and Seoul is challenging due to the 9 hours offset. Teams should prioritize asynchronous communication or specific 'handover' windows.
London Business Pulse
- Culture London business culture is generally formal but collaborative. "Flexi-Fridays" are common in the summer.
- Lunch Break Typically 1:00 PM - 2:00 PM.
- Pro Tip Avoid calling after 4:30 PM on Fridays as many offices wind down early for the weekend. Mid-week (Tuesday to Thursday) between 10 AM and 4 PM is the "Golden Window" for reaching decision-makers. Always start with a brief polite inquiry about their day before diving into business.
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.
