The fact that labor unions in general, and construction unions in particular, have not taken a strong stand against illegal immigration has always puzzled me.
An excellent question. Obviously, there is more to this problem than meets the eye. There's a lot of "backroom" conniving going on over this, but whatever it is, it is not in the interest of the American people, national security, or domestic tranquility. I think what you are getting at is that this coddling of illegal aliens is damaging to union interests and unionized workers, and to the economy overall (particularly to health care). Yet liberals (who are pro-union) seem to oppose anything which would really stem the flow of illegals (it's racist, inhumane, unjust, etc.) Doesn't make sense, does it? How can we have it both ways and remain a viable nation? I don't think we can.
They made the decision some time ago that rather than fighting for higher wages for shrinking bargaining units they would go for organizing the multitudes of potential dues paying illegal aliens. It hasn’t worked.

The labor unions are pushing as hard as the illegal rights organizations for amnisty for all the illegals so they can steal their money as dues!
