I am more'n willing to dialogue on the history of American unions, though organized labor history t'aint my speciality. However, I'd prefer it if we focused on the value (or loss of value) to the nation we receive from unions as they exist today. In my mind,there are various sorts of unions and they have different effects. Government worker unions. Teachers unions, postal worker unions, federal employee civil service/unions, police unions, American Federation of State, County and Municipal Employees, etc. American Federation of State, County and Municipal Employees - Wikipedia, the free encyclopedia Unskilled labor unions. I do not mean no one belonging to these unions has any skills; I mean that these unions admit unskilled workers. United Food and Commercial Workers International Union, Retail, Wholesale and Department Store Union, Transport Workers Union of America, United Mine Workers of America, AFL-CIO, etc. http://www.aflcio.org/ Skilled Labor Unions. International Brotherhood of Electrical Workers, United Association of Plumbers and Pipefitters, International Union of Elevator Constructors, etc. http://ibew.org/ If when posting, you mean that a good or bad effect follows from the activities of one type of union but not another, it'd be helpful if you clarified that.
