Avoiding frequent interactions with the office cleaners at coworkers gatherings is not an appropriate or respectful approach. Everyone should be treated equally and respected, regardless of their education level or profession. Cleaners work hard to keep the office clean and running smoothly, and they are also part of the team and deserve our kindness and tolerance. Instead, it is recommended that you actively communicate and interact with the cleaners, which not only reflects your politeness and accomplishment, but also helps to create a harmonious and friendly working atmosphere. You can sincerely thank them for their hard work, ask about their recent situation, share some lighthearted topics, etc. Such interactions can enhance mutual understanding and feelings and enhance the cohesion of the entire team. Treating every colleague with respect and equality is the basis for building good interpersonal relationships and making the working environment more positive.
