Can you please tell me is there demand for sys admins in Poland?
Have you tried looking at praca.pl or any of their rival recruitment platforms? Having said that, it's a slow period for recruitment right now due to Covid.
Poles didnt swamp the UK and didnt drag down the standard of living,
The people there who are anti-migration would (and do) strongly disagree with you.
Anyway, your opinions on recruitment (apart from being anti-Polish) don't help the person who's asked the question.
