Times has an article about the illegal immigrants working for Walmart.
Technically, they were working for subcontractors paying them off the
books to clean Walmart stores.
Last February, Pavel responded to an intriguing Web site that boasted
of cleaning jobs in the United States paying four times what he was
earning as a restaurant manager in the Czech Republic. He flew from
Prague to New York on a tourist visa and took a bus to Lynchburg,
Va., where a subcontractor delivered him to a giant Wal-Mart.
Pavel immediately began on the midnight shift and said he soon learned
that he would never receive a night off. He said he worked every night
for the next eight months. In this way, Pavel, who refused to give
his last name, became one pawn among hundreds employed by subcontractors
that clean Wal-Mart stores across the nation, paying many workers
off the books.
What a nice family company!! Here is a link of an employee
of Walmart who writes about his experiences working for them.
