Unions’ Pact Could Pose Problem for UPS

A coalition of independent pilots’ unions has drafted labor-solidarity principles that could make it harder for United Parcel Service to find alternative ways to ship cargo by air if its pilots strike next year. The coalition representing 28,000 pilots, including those who fly UPS’ cargo jets, agreed not to move cargo or passengers for an airline whose pilots are on strike. The 2,000 members of Louisville, Ky.-based Independent Pilots Assn. fly for UPS. Contract talks between the union and UPS are to resume Jan. 12.
