Hospital Beds: 50 to 99 (United States)

I am from the North, so I was in for a shock when I moved South. They have minimal employment rights here in North Carolina; even their Labor Laws says the employer can treat the employee "as they see fit." According to their laws, a dog is better off! In addition to this, I am realizing as other employees talk, more and more employees are making more money than me (a dollar and more) yet some were hired after me. The also have only a few years experience while I have eighteen years experience. This would never slide in the North. However, down here, there is some type of gag law where if you discuss your salary it is cause for immediate dismissal. Isn't this against First Amendment as well as Fourteenth Amendment Rights and Equal Pay for Equal Work rights? My salary as far as payscale.com states, is not even on the Richter Scale and is lower than the lowest marked on the scale. What is my recourse other than moving back North where people have rights?
