Through slashdot, I found an article on CNN.com this morning called Blog-linked firings prompt calls for better policies.
It’s an interesting read about the conflict that can occur between blogging and your job, covering people who get fired for things they’ve written because of inadvertantly “violating security” or just plain saying the wrong thing. It also explains that the first amendment does not mean you can just say anything you want, nor protect you from being fired for something you say. The main point of the amendment is to prevent government from restricting speech.
