The term Industrial Revolution 4.0 is very common nowadays, quite mysterious to most people and its content is unknown. It can be said with great certainty that it is already touching and will touch both production processes, radical changes in their structure, the advent of groundbreaking technological and communication devices, but it will certainly affect labour relations. The growth of new forms and methods of work based on automation, digitisation, applied also in new models of labour relations, is already beginning to threaten jobs in some segments of the economy. There are increasing demands for specific qualifications and skills for people, particularly in the field of information technology, with an emphasis on the digitisation of processes, data processing and the creation of communication networks linking objects and people. This smart industry will, understandably, disqualify many jobs without the need to keep them in their current structure, causing many employees to lose their jobs. Analysts openly say that by 2030, robots will replace up to 20 million industrial jobs worldwide. The idea of which jobs or occupations or working conditions in them will be affected is already becoming concrete. Radical change will require radical solutions, but also hitherto unrecognised movements and new elements and measures in the labour market. The Fourth Industrial Revolution offers a new direction and unique opportunities for the development of national economies. This major societal change will have a significant impact on the labour market, resulting in the creation of new jobs on the one hand, but with the inherent consequence that existing jobs will also be under threat.
