The bankrupt maker of the Twinkies snack, Hostess Brands Inc., is seeking court approval to impose a new collective bargaining agreement on 6,500 members of a bakery union, days after the union voted overwhelmingly against the deal, Reuters reported yesterday. Hostess said in court documents that imposing the labor contact, which cuts wages by 8 percent and reduces benefits, is the company's last hope to avoid a going-out-of-business liquidation. The Bakery, Confectionary, Tobacco and Grain Millers International Union said on Monday that 92 percent of its members rejected the labor contract.
