Yes - I'm talking about net income. I've a small mistake:
~ 10.000 Euro (not $) / year this is ~ 14.000$ / year.
Sorry to be inquisitive even further, I am not in Poland but my friend is thinking about moving there. Are you talking Warsaw here or a smaller town (Krakow, Wroclaw, Tricity area)?
I'm working in Krakow, but I know that salary in Warsaw can be much more higher.
