The United Food and Commercial Workers' union is asking the National Labor Relations Board to investigate whether Wal-Mart bribed employees to block union activities. These charges come after the Wall Street Journal reported that a former Wal-Mart Vice Chairman may have used undocumented expense payments to fund anti-union activities. A Wal-Mart spokeswoman says that there is no evidence to support the charges.
