I can only speak for UK contractors/companies, but most of these guys will immediately close ranks on you if you try and pull this. The guys at the lower end of the chain won't want to say anything because it could affect their ability to get work at a later date. A lot of them are on temporary contracts, and these companies talk to each other. If they start making noise about these sorts of mistakes, they could well wind up on a blacklist.
