"In 1986, the law expanded to include sanctions against employers who knowingly hire illegal immigrants."
"Barley said most farms' immigrant workers are here legally"
It's illegal to knowingly hire illegals. If the second quote was true, this would not be an issue.
No rain, farm subsidy. No sun, farm subsidy. This isn't going to be the end of farming either. When employers hire illegals below the prevailing wage, it drives away workers who are legit.

OK. So we're still talking ILLEGAL IMMIGRATION.
Paying illegals, under the table, no taxes, no workers comp or insurance.....

Hmmmmm. People will still buy milk, just like we're paying $3 for gas. Sounds like both the poultry and dairy industries need to overhaul some of their practices.
