The paper analyzes the labor market flexibility within the European Union. The labor market manages the supply and demand forces for work. Such a market includes workers who are looking for a job, their employment, workers who are employed, are satisfied or are looking for new jobs, competitiveness, work conditions and the like. On the labor market, it is traded with the knowledge, skills and experience of workers, on the other hand, by the amount of pay, working time and the more favorable working conditions. The labor market and all other markets are characterized by high competition, the best product will be the most expensive and the biggest demand for it. The European Union's labor market goal is to provide greater flexibility, freedom of movement for workers and social security for all. In order to achieve greater employment, greater social security, better education are implemented measures aimed at creating a flexible and secure labor market. Freedom of movement for workers is one of the four foundations of freedom that make up the common European market. With the entry of the Republic of Croatia into the European Union for the citizens of Croatia, the borders of free movement and employment have been opened within all the member states. Croatia is facing a huge wave of migration and emigration of the population.
