If you want to keep some colleagues at a distance in the workplace, here are some suggestions: 1. **Stay professional**: Always treat your work with a professional attitude, focus on the task itself, and avoid too much non-work-related communication with maintenance personnel. 2. **Set boundaries**: You can keep your distance by keeping your communication brief and clearly defining the boundaries of your work. You don't have to actively participate in personal topics. 3. **Use team communication tools**: Communicate through email or work groups instead of face-to-face communication, which can reduce unnecessary contact. 4. **Focus on work**: When working, stay busy and actively engage in your work, which will naturally reduce the opportunity to interact with others. 5. **Choice of participating in group activities**: If there are team activities, you can choose not to participate or keep a certain distance when participating. 6. **Friendly but keep your distance**: Even if you keep a certain distance, you must maintain basic courtesy and respect. When necessary, you can simply greet but not talk in depth. In this way, you can avoid establishing deep friendships with certain colleagues while maintaining a working relationship. Remember to respect others and maintain professional ethics. It is very important.
