In the workplace, it is understandable to maintain a professional environment and appropriate boundaries. Here are some suggestions to help you maintain an appropriate distance from maintenance personnel without being impolite: 1. **Stay Professional**: Maintain a professional attitude no matter who you are communicating with. Focus on work-related communications and avoid topics that involve your personal life. 2. **Brief Communication**: When communicating with maintenance personnel, try to keep the conversation short and direct, and focus on work-related topics. 3. **Set Boundaries**: If you feel that the other party wants to communicate in depth, you can politely set boundaries, such as indicating that you have other work to deal with. 4. **Utilize Workspace**: Utilize your own independent workspace as much as possible to reduce unnecessary face-to-face contact. 5. **Politely Avoid Off-Hours**: If you are asked to chat or socialize during off-hours, you can politely inform that you have other plans. 6. **Respect All Employees**: Although you may not want to get too close, it is important to be polite and respectful to all employees. Everyone contributes to the operation of the company, and a professional attitude contributes to the overall harmonious work environment. 7. **Value Communication Skills**: Practice effective communication skills and ensure that the message is clearly conveyed, laying the foundation for effective cooperation. With these methods, you can maintain a professional distance without losing respect and courtesy towards others.
