Even if from Catalonia (the poster here is not)
but he wrote
Hi everyone, my name is Pau, 28 years old, coming from Catalunya
and wiki says: "Katalonia (kat. Catalunya [kətəˈɫuɲə], hiszp. Cataluña, oksytański Catalonha) "
The relocation bill (if any) for hiring someone from Lublin, or Gdansk, or another town where salaries are less than Wrocław's, would surely not exceed that of relocating someone from another country.
But any Spanish financial controllers working elsewhere in Polnad could be not willing to move.
They are probably given tax incentives to set up shop in Poland and hire locals, yet their sites have head scratchingly large numbers of foreign national "managers" or whatever other "specialist roles" from their home country or elsewhere (in their hundreds if not thousands) and far fewer local Polish workers than should be the case. This seems to me to say that something is rotten in the state of Denmark.
Still it's good for the economy, because their workers pay taxes in Poland.
