Wal-Mart's in trouble again. This time for locking its workers in over night.

"My ankle was crushed," Mr. Rodriguez said, explaining he had been struck by an electronic cart driven by an employee moving merchandise. "I was yelling and running around like a hurt dog that had been hit by a car. Another worker made some phone calls to reach a manager, and it took an hour for someone to get there and unlock the door."

Apparently, for the past 15 years Wal-Mart has had a policy of locking its employees in many of its Wal-Mart and Sam's stores at night to reduce crime.
