When taking a message for a co-worker, which detail is least important to include?

When taking a message for a co-worker, including the length of the call is least important compared to the other details. The primary focus in message taking is on ensuring that the vital information is conveyed so that the recipient can follow up effectively. The phone number of the caller is necessary for direct communication, the name of the caller provides context and personalization, and the time of the call can be crucial for understanding the urgency or relevance of the message. While knowing how long the call lasted might provide some insight into the discussion, it does not impact the effectiveness of follow-up actions as significantly as the other details. Therefore, prioritizing those core pieces of information ensures that the message relayed contributes to clear and efficient communication in a professional setting.
