A growing number of major employers are monitoring social network sites and using information gathered to discipline and/or terminate their employees. Many of these companies, including UPS, have issued social media guidelines to their employees outlining what is acceptable and what is not. I have no problem with employers disciplining and/or terminating employees based on information gathered from social media networks. I don't facebook but if I did I wouldn't post anything there that I wouldn't say face-to-face. I also wouldn't post anything that would/could portray my employer in a negative way.
