Employers must have the ability to review everything on their computer systems to make sure that there's no illegal activity being conducted. If someone conducts criminal activity using an e-mail system, unknown to the company, the company's e-mail system can be subject to seizure. Or an employer may be sued in a breach of contract case. As part of that they're going to have to go through a lot of employee e-mail.  -   Michael Overly     Quotes
