I think you may have misunderstood what I meant. I meant that if people were colluding to not hire people from various companies, it would make sense that the Federal government is involved, as that would be a problem.

If it is just a "we won't actively recruit", then it doesn't make sense to me. This seems a valid thing to do. Actively recruiting vs. denying hiring are two radically different things, and the Feds getting involved in the decision of where to recruit from seems silly.
