St Louis Business Pulse
- Culture Midwestern values of friendliness and hard work. Business is professional but often involves personal connection.
- Lunch Break Typically 12:00 PM - 1:00 PM.
- Pro Tip Operating in Central Time (CST/CDT), St Louis is a perfect bridge for coast-to-coast US calls. Reach out between 9:00 AM and 11:00 AM for the most engaged responses. A friendly, personal opening is culturally expected before diving into technical or business details.
Sydney Business Pulse
- Culture Relatively relaxed but professional. Early starts are common to maximize daylight.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Due to the significant time difference with Europe and the US, early mornings (8:30 AM - 10:00 AM) are often dedicated to international syncs. For domestic calls, late mornings are best. Be mindful that many Australians start and end their day earlier than their Northern Hemisphere counterparts.
