Members of the International Association of Machinists and Aerospace just signed a new contract with East Hartford based Pratt & Whitney.

International Association of Machinists and Aerospace members at both Connecticut facilities manufacture, repair, and produce parts for commercial and military engines, including the KC-46 air refueling tanker, F-35 joint strike fighter, and the A320 commercial airliner.

Union leadership says the new contract has increased wages, job security and decreased health care insurance costs for the union’s 3,000 members.
