Perhaps someone with more knowledge of them can speak to this, but I know in some circles there is a belief that unions tend to commoditize their workers, practice if not in theory. I do not know if that is true, but I do know that I absolutely do not want my services to be a commodity. I work hard to try to get into the upper echelons of a highly differentiated field, and I would seek to either differentiate myself or change fields to a more differentiated one if it began to appear that my services could easily be commoditized.
