Don't forget that Polish professionals in the uk are highly valued for their work ethic and commitment.
Not any more, its the Romanians and the Bulgarians now. The Poles have become some what selective, and in my line of work i find them bringing their Polish work ethics to the work place more and more.

What you basically need as an employer is somebody who's tasted poverty or better yet trying to escape poverty, these guys work and work. Gotta love capitalism.
