You unintentionally offend foreign workers by using their first names. What is the worst response?

Choosing to thank the worker for bringing the issue to your attention but making no changes is the least appropriate response in this situation. This approach dismisses the worker's feelings and concerns and fails to acknowledge the cultural sensitivities involved. It does not demonstrate a willingness to learn from the experience or adapt future behavior, which is crucial in a multicultural environment.

In international contexts, addressing others in a manner that aligns with their cultural norms is important for fostering respectful communication. Ignoring the feedback and not making any efforts to change your behavior can perpetuate misunderstandings and resentment, suggesting a lack of respect for the other person's culture and preferences.

On the other hand, responses that involve an apology and a willingness to understand the proper form of address (as seen in the other choices) reflect respect and an openness to improving communication. These approaches show that you value the relationship and are committed to creating a more positive environment.
