Both parties have the freedom of choice regarding the form of labor contract. However, the definition of workers is the pivot when we argue about its legal character. The insurance solicitors can serve as examples. Labor law is mainly about personal subordinate relation and it is followed by legal practices. This causes ambiguity and dilemma, such as combinative applications and mix contracts as well as creates confusion over the essence of workers, which is constructed by subordinate relations. On the other hand, the alternative approach, emphasizing on economic subordinate relation and the need of social protection, replaces subordinate relations with non-dependence. This approach focuses on control and commitment and thus enriches the diversity when we are managing relevant issues.
