Update: Thanks readers, below is the exact text in question out of the Employee Handbook:
Internet/Blogging PolicyDarden supports the free exchange of information and supports camaraderie among its employees. We also are extremely proud of our reputation of being “The Best in Full-Service Dining” and of the strong brand identities we have created. Consistent with our company’s overall employee code of conduct, Darden employees must always express themselves in a manner that is professional and respectful when engaging in social media. When internet blogging, chat room discussions, e-mail, text messages, or other forms of communication reveal confidential and/or proprietary information about the Company or include inappropriate discussions about co-workers, guests, or others, the employee may be violating the law and is subject to disciplinary action, up to and including termination of employment. Please keep in mind that if you communicate regarding any aspect of the Company, you must include a disclaimer that the views you share are your own, and not necessarily the views of the Company. This applies to statements made during work and non-work hours and in any communication medium (Facebook, Twitter, YouTube, My Space, e-mail, text messages, videos, etc.).
