In the workplace, it is inappropriate and disrespectful to avoid close friendships with office building maintenance personnel. Everyone has their own value and dignity. Regardless of their educational level, they should be treated with equality, kindness and respect. Maintenance personnel play a vital role in the normal operation of office buildings. Their work ensures the comfort and safety of the office environment. Here are some more appropriate suggestions: - **Be polite and respectful**: Always treat maintenance personnel with courtesy and kindness, and express recognition and gratitude for their work, which will help to establish a good working relationship. - **Focus on work communication**: When communicating with maintenance personnel, focus on work needs, maintenance tasks and problem solving to ensure smooth work. - **Respect personal space**: Everyone has their own personal life and work rhythm. Respect the personal space of maintenance personnel and do not disturb them too much. Abandon the prejudice caused by academic qualifications, get along with them with an open, inclusive and equal attitude, and jointly create a harmonious and collaborative working environment. This will not only be conducive to the development of work, but also reflect your professional quality and humanistic care.
