I got this article from www.lilsugar.com it says:
A Massachusetts teacher should have taught herself this lesson: don’t post anything on social networking sites that you want to keep private. June Talvitie-Siple was forced to resign after she made unfavorable comments about students and their parents on her Facebook page.
Talvitie-Siple used the terms “germbags,” “arrogant,” and “snobby,” believing that she was talking with friends, but the comments were public. The educator also wrote that she was less than enthused about the upcoming school year. Would you be upset if your child’s teacher vented his or her frustrations on a social networking site?
