The work of foreigners in Croatia represents a very important segment of the modern labour market. In its past, Croatia was, unfortunately, primarily a country of emigrants. Emigration has, among other factors, brought Croatia into an extremely unfavourable demographic situation, which consequently led to labour shortages, especially in sectors such as construction, tourism and healthcare. The problem of labour shortage is being solved by "importing" foreign workers. In previous years, most foreign workers came from our neighbouring countries, that is, from the countries of Southeast Europe. It was relatively easy to integrate these workers into Croatian society. However, recently there has been an increasing influx of foreign workers from distant countries like Nepal, India and Bangladesh. In one hand, this presents great challenges that include language barriers and cultural adaptation, and on the other hand it provides an opportunity for economic growth and development. Croatia has regulated the work of citizens of third countries until 2021 according to the so-called quota system. That system did not meet the needs of employers and was poorly adaptable to sudden changes in the labour market, therefore it was replaced by a new, more flexible one. The currently enforced system is based on the so-called labour market test. Given that labour relations and the labour market is a very dynamic area, the existing legal framework that regulates work of foreigners will need to be changed and supplemented to be better adapted to the existing needs and challenges of the labour market.
