This was a really ugly blot on Carnegie's legacy...hope Sir Tom Hunter doesn't TOTALLY model himself on Carnegie.
The Homestead Strike One of the most difficult episodes Andrew Carnegie's life -- and one that revealed the steel magnate's conflicting beliefs regarding the rights of labor -- was the bitter conflict in 1892 at his steel plant in Homestead, Pennsylvania. Carnegie's involvement in the union-breaking action left many men dead or wounded and forever tarnished Carnegie's reputation as a benevolent employer and a champion of labor.
The conflict at Homestead arose at a time when the fast-changing American economy had stumbled and conflicts between labor and management had flared up all over the country. In 1892, labor declared a general strike in New Orleans. Coal miners struck in Tennessee, as did railroad switchmen in Buffalo, New York and copper miners in Idaho.
Carnegie's mighty steel industry was not immune to the downturn. In 1890, the price of rolled-steel products started to decline, dropping from $35 a gross ton to $22 early in 1892. In the face of depressed steel prices, Henry C. Frick, general manager of the Homestead plant that Carnegie largely owned, was determined to cut wages and break the Amalgamated Association of Iron and Steel Workers, one of the strongest craft unions in the country.
Behind the scenes, Carnegie supported Frick's plans. In the spring of 1892, Carnegie had Frick produce as much armor plate as possible before the union's contract expired at the end of June. If the union failed to accept Frick's terms, Carnegie instructed him to shut down the plant and wait until the workers buckled. "We... approve of anything you do," Carnegie wrote from England in words he would later come to regret. "We are with you to the end."
