What goes on Facebook, stays on Facebook. What you post can get you fired, doctor or not. You represent the company you work for, and negatively speaking of said company, supervisors, and other associates, can be held against you when you post it publicly (even if your settings are private). Every action has a reaction. She is a professional and should have thought about that BEFORE she posted a rant on a social media site. As for HIPAA, she did not list any identifying information, but it was still in very bad taste!
