I once read that the concept of human rights has not been an important influence in the making of United States labor policy. In this country, workers are considered to have only those rights set forth in specific statutes or collective bargaining contracts and those statutes and contracts are subject to shifting political and bargaining power. Discuss the validity of these statements by using each of the four schools of thought about employment relationship discussed in chapter 2 as your basis. (Note: You can input "the four schools of thought about employment" into Google and click the first link, which is a PDF for Chapter 2 content)
