Though the European countries are bound together by economic and free movement treaties, each & every country is responsible for its own economic status & this is the reason for the vast difference in cost of living & PayScale between countries in Europe. Probably you have heard about
the countries “Austria” & “Slovakia”. Both the countries are part of European Union & also Schengen Members. More importantly both these countries share a common border. The capital of Slovakia (Bratislava) is just 80 Kilometres away from the capital of Austria (Vienna). However, the cost of living in Vienna is about 4 times more expensive than in Bratislava. Similarly, the average salary for a job in Vienna is almost 3-4 times much higher than the same job in Bratislava.
Poland is a country which is widely considered as a country with low cost of living & also with low-medium income pay. Due to this fact, multiple Global corporations have their operations in Poland.
This in turn is providing a wide range of career opportunities for employees in Poland.
