Refrain from any behavior that could be harmful to the company, its employees and its clients. When on business travel, you're expected to comply with all company policies. Hard limits on employee behavior include: No harassment or discrimination.

On a 2026 business trip, the most critical mistake is blurring the lines between professional and personal conduct. You should never overindulge in alcohol during "off-hours" or client dinners, as your behavior is always a reflection of your company. Avoid sharing confidential company information in public spaces like hotel lobbies or airport lounges, where "shoulder surfing" or digital eavesdropping is common. Additionally, do not skip the cultural research; for instance, failing to understand local etiquette (like bowing in Japan or the importance of punctuality in Germany) can ruin a deal before it starts. You should also avoid excessive "expense padding"—modern 2026 AI auditing tools can easily flag irregular spending patterns. Finally, never treat the trip like a vacation at the expense of your productivity; being "out of office" does not mean being "out of touch" with your core responsibilities.
