To the original poster. I don't know whether you are union or not, but if you're making 20 an hour as a helper, I would not complain. Albeit, if this particular contractor is committing fraud, he should be busted and prosecuted. You'd better find out the explicit facts before you act. You're the one responsible for making your own living. I know a lot of skilled people who would relish a 20 dollar an hour job. If you act and find out you're wrong, well in reality, you could screw yourself pretty bad if this contractor is vindictive and has influence. All I'm saying is find out the facts and think about it before you go making a stink.
