Which of the following should email not be used for?

Email is generally considered an inappropriate medium for delivering sensitive messages such as firing someone due to its impersonal nature. When it comes to termination of employment, it's essential to handle the situation with care, empathy, and direct communication, ideally in person or at least over a phone call. This allows for a more respectful and supportive environment, where the individual can ask questions and receive necessary guidance in real-time.

In contrast, other options, like sending work-related updates, sharing project documents, and asking for a meeting, are typically appropriate uses of email. These types of communications are often straightforward and do not carry the same emotional weight or potential for misunderstanding that a termination would entail. Using email for these purposes helps maintain a clear documented record, making it suitable for standard workplace communication.
