A group of fired Wal-Mart workers in Utah is fighting a store policy they say leaves them powerless to defend themselves even if their lives are at risk.

An attorney for six former employees argued before the Utah Supreme Court on Wednesday that workers shouldn't have to choose between their safety and their jobs. The case stems from three instances, one in which workers grabbed a gun away from a shoplifter in Layton.

Wal-Mart says the workers violated the chain's policy of walking away when people become belligerent. A Wal-Mart attorney told the justices the policy is designed to keep customers safe by preventing confrontations that could get out of hand.

No immediate deadline was set for a ruling from the high court.
