Final answer:
In a business context, it is proper etiquette to ask for permission before putting a caller on hold, reflecting respect and good customer service practices.
Step-by-step explanation:
When managing phone calls in a business context, etiquette is important. If putting a caller on hold is unavoidable, you should first ask the caller for permission to do so. One should politely say, "May I place you on hold for a moment?", ensuring the caller's needs are respected.
This courteous approach aligns with general principles of customer service and professional communication. Additionally, just like applying the social rule of placing the napkin on one's lap after sitting down at a dining table, or considering how long to await on a call with someone who has call waiting, asking for permission to place a caller on hold reflects good manners in a business setting.
