 A trade association formed in August to represent the interests of driver contractors at parcel delivery firm FedEx Ground disbanded on Friday amid allegations by the groups founder that the FedEx Corp. unit threatened to strip its leaders of their contracts if they kept the group alive. In a statement distributed Thursday night, the 10-member leadership committee of the Trade Association for Logistics Professionals TALP said the group was not the appropriate vehicle to promote effective dialogue between the FedEx NYSE: FDX unit and the 6,000 nationwide delivery contractors who operate exclusively for it.
