I have written a number of blogs on cybervetting and social media. One important case involved an ambulance company, American Medical Response of Connecticut that had fired an employee, Dawnmarie Souza, for criticizing the company on Facebook. The National Labor Relations Board argues that employers are in violation of the law when they fire workers for engaging in work related conversation, even negative ones, on social networking sites. This case was settled before it went to trial with the companyÂ agreeing to make changes to its policy.
For a description of the settlement see the New York Times.
