National Law Journal:  “Employers must address their use and misuse before, during and after an employee’s tenure.  Social media are any type of Internet-based media created through social interaction in which ­individuals primarily produce, rather than consume, the content. In the workplace, the prevalent social media are video-sharing Web sites (YouTube), social ­networking Web sites (Facebook, MySpace, LinkedIn, Twitter), online multiuser virtual worlds (Second Life, World of War­craft) and personal or corporate blogs.  The increased use of social media in the workplace, by employees and employers alike, presents both opportunities and risks for employers because social media now permeate the entire life cycle of employment: during pre-employment inquiries, throughout the period of employment and after separation from employment. Employers must consider and address the use and misuse of social media at each stage.”
