You may be dying to tell the world about your new work promotion, but if it's news that could be advantageous to one of your company's competitors, then it's not something you should share. News of a planned expansion or a big project role and anything else about your workplace should be kept private. Sophos, a security software company, found that 63 percent of companies were afraid of what their employees were choosing to share on social networking sites [source: ReadWriteWeb]. If you want to message it out, be selective and send private e-mails. Many companies are so serious about not being included in social networking sites that they forbid employees from using sites like Facebook at work. Some IT departments even filter the URLs and block access to these sites altogether so employees aren't tempted to log on.
