Yes, they do, they don't really have a choice, living in a tough capitalism we have ;)
I've never noticed urządniki working particularly hard.
Yes, 'urzedniki' is another story, a relict of communism age. :D Often they work where they work bacause they have some family commections (also a relict of comunism). They are a real pain in the ass sometimes, they can be rude and reluctant to changes and upgrades in a workplace. But I know a few young ones, and they are working really good, and have a different attitude. Of course they are being used by those old 'urzedniki' to do all the job.. Anyway, they are a hope for the future.. Anyone else except of urzedniki, and a few people who have great jobs, and won't get fire no matter what they do, because they are sb' childeren, have to work real hard, and often one person is doing duties of 2 or 3 persons, because it is cheaper for the employer that way.
Let's say you're a building worker. You're earning a good wage. You've got a mortgage and family to support. Then someone offers to do your work at half the price you were paid. Happy?
I see your point. But then you should force your government to set minimum wages for certain professions, they did so in Norway, and nobody can earn any less. And of course employers prefer to hire Norwegians then, unless they have ral shortage if staff in certain proffesions. I don't think focusing your anger on unaware immigrants will solve anything..
