Rights and Principles: The web

Labour Law’s new challenges should take us back us to its basis: the Principles of Labour Law.
But what is a Principle and what are its functions?
Principles of Labour Law are adaptations of General Principles of Law; the Protection Principle, on which Labour Law is based, includes the General Principle of Compensation.
Principles are basic rules of human behaviour and of law application and they are the pillars of the legal system, together with human rights, having their same supraconstitutional hierarchy and universal nature, creating both the web of the Universal Labour Law.
Principles are general and abstract but, because of that, they solve specific issues, such as the scope of Labour Law, determining the connecting factors and the applicable legislation in international labour cases, and the scope and limits of collective autonomy.
