Maybe so, but that wasn't really the discussion regarding New Orleans. New Orleans was brought up by another poster in regards to union vs non-union wages in comparison to other departments in your state. There was no connection to the Civil Service System until you stated that New Orleans was not Civil Service, which really had no bearing on the union vs non-union wage discussion. Participation in the state Civil Service System may require certain things regarding compensation, like the 2% annual raise you stated, but a Local can negotiate a larger raise and a non-union department could provide a larger raise and the ability to do so has absolutely no connection to the Civil Service System. So the state Civil Service System really had no relevance to what was being discussed regarding compensation. It was only relevant to the discussion showing that you were wrong about New Orleans not being Civil Service.
However, the fact that they are not part of the state system does have relevance when we are discussing the state system's and the union's impact on wages and benefits in every other department in the state that is mandated to be civil service.
