This article looks at how normative questions, i.e. ‘what should the law be?‘, are approached in modern labour law scholarship. A distinction is made between internal and external normative frameworks for analysis, whereby internal frameworks are made up of principles, values or standards that are part of the law and the external frameworks are made up of theories outside of law. As a functional legal field, labour law can also benefit to a great deal from empirical research. However, the article argues that empirical facts by themselves have a limited normative value and that we need a normative framework in order to answer normative and evaluative questions. Therefore, the aim of the article is to review, clarify and evaluate the internal normative framework of labour law.

This paper discusses three approaches that can be helpful in the area of comparative rights jurisprudence, oriented in reference to three different kinds of studies that are possible in that area. To a large extent the methods for a comparative legal research depend on the research question and the goal of the researcher. First, a comparative law study may focus on the sociocultural context that led to the elaboration of differences or similarities in the protection of rights. Second, a comparative law approach can be a normative enterprise. It can focus on engaging in a philosophical analysis enlightened by the differences or similarities in the regulation of rights, in order to propose concrete solutions for the regulation of a right. Third, a comparative law approach can combine both elements of the two previously mentioned approaches. The paper discusses the challenges that the researcher faces in her attempt to use these methodologies and how these challenges can be overcome. The law as a normative discipline has its own constraints of justifiability. If what motivates a comparative law study is the search for principles of justice the researcher needs to persuade that her methodological approach serves her aim.
