I've employed about 20 Polish this year and every single one has turned out very bad for us. Never, ever again.
( come to think of it, ONE was OK, but 1/20 is awful). What makes this worse is that they have all come to us via our local Catholic Church. Think long and hard before going down this route, I wish I had. Nice as pie to your face, but running you down to your clients behind your back and trying to steal the work. Trouble makers, untrustworthy, militant know-alls.
