The article is devoted to a analysis of the evolution of case law on employer liability for termination of employment contracts. The judgment of the Constitutional Court of November 27, 2007. SK 18/05 represented a revolution in the system of liability of the parties to the employment relationship. However, it did not resolve a number of important issues, which were left to the Supreme Court. These issues – for the most part – have already been resolved, but what is interesting is that over the years the position of the Supreme Court has undergone a fundamental evolution. The author presents this evolution and draws attention to some – continuing – doubts.
