The government has said it plans to crack down ever harder on employers who harbor and hire illegal immigrants, pursuing companies that ignore the law so they can exploit cheap labor. In one such crack down, federal agents on Wednesday arrested seven current and former managers of IFCO Systems, a manufacturer of crates and pallets, on criminal charges, and more than 1,100 people were arrested on administrative immigration charges at more than 40 IFCO sites in the U.S.
