They're not against Unions. They're against forced dues and corrupt union leaders. They're against forced entry into the union. Some states are right-to-work states, but even so, if a particular industry is "union" such as the Railroad, we're against forcing a person to join the union. There have been some great things brought about by the Union as you mentioned, but right now, the Union has exceeded it's intended scope and in many instances become organized extortion groups.
