In the workplace, maintaining polite and respectful interaction with colleagues in different positions is a manifestation of professionalism. If you want to reduce non-essential social contact, you can balance your sense of boundaries with basic etiquette in the following ways： **1. Convey boundaries with actions, not attitudes** -Take the initiative to smile or nod, but avoid opening small talk topics (such as not taking the initiative to ask about private life or extend the conversation) -Use "nonverbal signals": wear headphones to focus on work, place "at work" signs in the station, and use the actions of organizing the desktop or focusing on operating the computer to convey the busy state. **2. Optimize personal habits and reduce exposure to scenarios** -Instantly sort and discard waste items into public trash cans, instead of accumulating at workstations waiting for cleanup - Bring your own water cups and cutlery to reduce the amount of garbage generated by the use of disposable items - Store important documents in time to avoid frequent sorting due to clutter on the desktop **3. Direct needs can be expressed politely and clearly** -If you need to adjust the cleaning time, you can use neutral reasons to communicate (such as "I often need online meetings in the afternoon recently, can you please avoid cleaning at 2-3 o'clock?" ") -Special needs for working methods can be fed back to the administrative department to avoid direct requirements for cleaning personnel **4. Be wary of hidden biases and respect professional values** - Academic qualifications have nothing to do with professional dignity: cleaning work ensures the health and order of the office environment, and its professional value should be recognized -Avoid the thinking inertia of "reduce interaction = avoid contact with specific groups", which can be regarded as a general way to optimize personal time management **Sample scene processing：** When the cleaning staff cleans, they can pause the work at hand for 3 seconds, smile and say "Thank you for your hard work", and then continue to focus on the screen. Not only to express gratitude, but also to indicate the working status through body language. In the workplace, respect for others is reflected in equal treatment of the contributions of each position. The establishment of clear work boundaries should be based on efficiency requirements, not hidden judgments about occupation or background.
