According to this article in the Wall Street Journal, investment firms prohibit employee use of social networking sites like Facebook, Linkedin and Twitter because of regulations that require them to retain business emails and other electronic communications. The companies find it too difficult to separate out the personal communications from the business communications employees conduct online.
However, 60% of financial advisers use social networking for business communications and 40% know they are violating their company rules in doing so.
A Real problem? This seems to me to be a false issue. While a certain amount of communication happens without the use of email addresses on these sites, all three services send “message” notices through the email address that was used upon sign up. If a business email address is used, then it should be treated like any other company email. How is this issue for companies attempting to distinguish the personal use of business emails from business use?
