You send an email to a co-worker from your work computer. In the email, you complained in length about a customer that you had been interacting with. Once you push send, whose property is that email? Who is responsible for the context of the email if it is offensive to a coworker who receives the email - you, or your company? What if the email is not offensive to the recipient coworker, but is seen by the customer that you were complaining about? Who is responsible for the context of the email then? You who sent the email, or your business? Are your emails private?
