If you want to politely reduce your interactions with cleaners in the office, here are some tips to consider: 1. **Choose the right time**: You can work outside of the cleaners' working hours, such as choosing to do important work during the time when they are not cleaning. 2. **Use non-verbal communication**: Show courtesy through non-verbal means such as nodding and smiling, without too much verbal communication. 3. **Set up work areas**: If possible, you can set up some cleaning areas in the office and designate the areas where the cleaners clean to reduce the impact on your work area. 4. **Use headphones or other tools**: If you need to concentrate while working, wearing headphones can effectively reduce unnecessary interactions. 5. **Simple and clear communication**: If you must communicate, use simple, direct words to indicate that you are busy or need to concentrate, and try to minimize the time of interaction. 6. **Be polite and respectful**: When interacting with cleaners, always be polite and respectful. No matter how much interaction, a good attitude is important. Remember, respect everyone's work in any situation, and their work is equally important.
