Pratt & Whitney Canada said yesterday it planned to lay off 1,000 workers in the coming months, due mainly to falling demand for the engines it supplies to business jet makers. The cuts will affect some 10 percent of the company’s global workforce, 7,000 of whom work in Canada and the remaining 3,000 in other countries. The company hasn’t yet exactly identified which factories the decision will affect most, a spokesman told AIN, nor has it decided on an exact date for when the layoffs will start, only that they would happen “a few months from now.” He did confirm that the overwhelming majority, if not all, of the cuts will involve jobs tied to business jet engine programs, however. “We are still…talking to our business aviation customers around the world and going through a full assessment before we can determine how it will unfold at each of our facilities around the world,” he said. “By the way, as it stands today, the other segments that we’re involved in such as helicopters, regional aviation and general aviation for the smaller aircraft are still going relatively well.”
