The bankrupt Trump Taj Mahal casino received court approval on Friday to break its labor agreement, a key condition for a rescue deal with billionaire Carl Icahn, and the union promptly announced a plan to picket the Atlantic City, N.J., hotel, Reuters reported yesterday. Parent company Trump Entertainment Resorts Inc. has said that trimming $14.6 million from its annual union pension and health care costs is key to saving the casino from becoming the fifth to close this year in the seaside resort. Bankruptcy Judge Kevin Gross said during a hearing that he would approve the request and would explain his reasoning in a written opinion this week. The Unite Here Local 54 union will appeal the ruling, the union's lawyer, Kathy Krieger of the law firm James & Hoffman, told the court.
