Surveys show that 35 percent of American adults have a profile on a social networking site. Seventy-five percent of Facebook
users admit to checking their Facebook at work, on company time and company-owned equipment. In 2004, more than 10 percent
of employees spent more than half of a day on email (86 percent of which is personal), and more than one in five employers
(21 percent) had employee email and instant messages subpoenaed in the course of a lawsuit or regulatory investigation. One
hundred percent of information placed on the Web is never really “erased” completely (Pew Internet Project, 2008).
