A worker who was allegedly fired for posting negative comments about her supervisor on her personal Facebook page is being championed by the National Labor Relations Board, which announced yesterday that it filed a complaint against the company.

The NLRB’s Hartford office sued American Medical Response of Connecticut, Inc., alleging that the ambulance service illegally terminated the employee, Dawnmarie Souza for the postings, and that the company wrongfully denied her union representation during an investigatory interview. NLRB also charged that the company “maintained and enforced an overly broad blogging and Internet posting policy.”
