Behnen's undoing, however, was a dispute with the unions that represented some of the Horseshoe's employees. In November 2002, the Culinary Workers Union and Bartenders Union filed a complaint with the National Labor Relations Board alleging that Behnen hadn't signed a collective bargaining agreement and had fallen behind on medical insurance and pension payments. The parties reached a settlement in March 2003 in which the Horseshoe signed the collective bargaining agreement and agreed to pay the owed money. However, the Horseshoe fell behind on its payments, leading a federal judge to issue two separate judgments ordering the Horseshoe to pay over $1.5 million. The judgments gave the union the right to seize the money if regular payments weren't being met.
