Final answer:
It is best practice to check back with callers on hold every 1 to 2 minutes, to acknowledge their time and maintain good customer service.
Step-by-step explanation:
When placing callers on hold, it is considered best practice to check back with them every 1 to 2 minutes to ensure they are still there and to reassure them that they have not been forgotten. This courteous behavior acknowledges the caller's time and patience. Staying in constant contact is crucial in providing good customer service and avoiding replaced relationships; the caller should feel their concerns are being actively addressed, akin to following up on a promise, similar to marking a calendar to remember a call about a job application status.
