U.S. Steel
The union attempted to organize workers in the tin industry, but a sudden wave of industry consolidations left the union facing the gigantic U.S. Steel corporation. In the U.S. Steel Recognition Strike of 1901, the union struck the fledgling company and won nearly all its demands. But the union's executive board wanted more and rejected the pact. U.S. Steel was able to muster its resources and break the strike.
