According to Document D, the testimony of a machinist before the Senate shows that there was a rise in unskilled labor. Employers no longer needed as much workers to do the same tasks. That factor as well as wage cuts and panics led to more strikes. The Knights of LaborÐ²Ð‚™s failed when conflict emerged between skilled and unskilled workers. Also, the exclusion unskilled labor by the American Federation of Labor gave them succeeding advantage over the Knights of Labor since skilled labor was harder to replace and valued to a great extent. The AFL had a lot of support to use to their advantage against the employers which was the reason for the split.
