In preparing to present a class on using social media in education, I came across this video about a teacher who was forced to resign after parents saw some of her Facebook status updates. http://www.youtube.com/watch?v=zU8m-4_CmtU
A little common sense: Don’t post complaints or sarcastic remarks on Facebook or any other social media sites. First of all, as you can see here, it can get you fired. Secondly, nobody really wants to hear you complain in person, let alone publicly on the Internet. Thirdly, please LEARN how to adjust your security and privacy settings.
It’s really just common sense!
