A hotel owner that recently came out of bankruptcy is rekindling a lawsuit against Marriott International Inc., saying that the company secretly helped the hotel's employees form a union that helped tip the Manhattan hotel owner into chapter 11, Dow Jones Newswires reported yesterday. In its amended complaint now recognized as the official complaint of record with New York State Supreme Court, lawyers for Madison 92nd Street Associates LLC said that Marriott officials indicated they would not push for the workers of the hotel to unionize, but then helped them do just that. The move, Madison 92nd said, led to higher costs for the company and eventually made them raise the prices for their rooms, which directly benefited competing properties in New York owned by Marriott that were selling for lower prices.
