Abstract
This paper is the result of research which the author´s team conducted on Czech, European and international labour law, specifically in regards to cases in which an employment relationship contacts two or more legal systems of different states. "Conflict of law" rules have led to the development of specific conflict rules that determine the applicable law in a particular case. The most favoured criterion for determining the applicable law is the place of permanent workplace.
The conflict rules governing the conflict of different labour law systems also implement the principle of employees´protection, which is significant for the entire body of labour law. The legal approach to determining the appropriate law is complicated in civil law because of several problems.
