The heated battle between the United Auto Workers and Foxwoods Resort Casino in Connecticut intensified on Friday when the UAW filed a complaint with the National Labor Relations Board. The UAW alleges that the casino forced employees to testify during recent hearings concerning a union election at the casino. According to the complaint a dealer said she did not testify for Foxwoods voluntarily. The union alleges that the casino interrogated employees prior to their testimonies. The UAW is seeking to represent the dealers at the casino.
