Ukraine is preparing for a radical overhaul of the labor code. According to experts, the changes will cause a new wave of emigration, and Ukraine is already suffering from labor shortages and will not be able to cope without immigrants.

The Ukrainian government is trying to stop the emigration to the West, including Poland. However, there are few signs that the it could succeed in its efforts.

There are more than 115 million immigrants currently living in developed countries of the OECD - people born outside their current country of residence who hold citizenship of the country of their origin. They constitute approx. 10% of the population in the OECD.

Last summer, having pondered his professional opportunities for some months, Istvan Kozari upped sticks, leaving his native Budapest for a new life in London. Mr Kozari, then just 35, had worked as a sales and marketing manager with a leading digital publisher in Hungary, and tried his hand working with Hungarian start-ups. But to further his career, the move was essential.

Poland is one of the leading OECD countries, but not in spending on research and development or pre capita income – instead, Poland is a leader in supplying foreign countries with emigrants with higher vocational and university education. The consequences are severe. Therefore, it is not surprising that arguments about the need to open ourselves to immigrants from the East are increasingly common.

Low population growth and economic emigration may lead to a sharp crisis in Poland's pension system and public finances. This can be prevented by a conscious family policy and economic immigration to Poland, especially from countries that are culturally close to us. We should be particularly eager to attract young and educated people. Is this realistic?

Ukraine's Maidan revolution, the seizure of Crimea by Russia, war against Russian-backed separatists in the east of the country and a deep economic recession have sent a torrent of Ukrainians either seeking shelter elsewhere in Ukraine or escaping east to Russia or west to the EU in search of a better and safer life. The figures are devastating: over 850,000 internally displaced persons and many more who have fled abroad.
