Email etiquette, use or leave it?
They say there is no such thing as privacy over the internet, so you have to be careful of what you say. This is most applicable in a corporate setting, where e-mail is commonly used as a form of communication.
Have you experienced sending an e-mail to a colleague, not receiving any response after a day, then wondering if the recipient did get your message? If part of your everyday routine at work is to check your e-mails, more so should responding be on your list. Not responding nor acknowledging e-mails that require replies would make the sender feel ignored.
This once happened to a close friend and I bet you would not wish the same. She was a
essay writer, venting her frustations toward her boss but have clicked 'reply all ' instead of 'reply.' The next day, everyone's talking about it and you could just guess what happened even worse than that. She was fired.
We do not have to go through the bitter part ourselves to learn a lesson. Company e-mail is not, and will never be private. As much as you want to curse an extremely rude officemate, you would rather keep things for yourself.
