You can hate your boss on Facebook without repercussions, says the National Labor Relations Board. The fallout could be that hundreds of companies (and even, say, Universities) have social networking policies that are illegal? Or maybe it doesn't mean that. I am not a lawyer. But a law firm warns companies that they should review their policies and make sure that they do not violate protected speech. It seems I've seen a lot of stories about people fired over Facebook posts (sometimes not even relating to their actual work). I'll be watching this one closely.
