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.
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.
