Email allows us to continue to work at home. Constant access leads to a compulsion to keep the communication going. You're at home, and there's nothing good on TV so you decide to have a glass of wine and do a little work. As you review your inbox, You don't you start firing off responses. Then suddenly you send an email to the wrong person. You don't want them to read it and the next thing you know you're sending even more emails to try and undo the damage. Another round of emails has begun!
