Rolls-Royce plans to cut 9,000 jobs.
The news comes after the aviation industry suffered massively in the wake of coronavirus.
Job losses from its global workforce of 52,000 are expected to be cut as part of a "major reorganisation" of the business.
Rolls-Royce's Scottish branch in Inchinnan, Renfrewshire focuses on engines from the original Hillington and East Kilbride factories.
The company said the cuts could result in £700 million in savings towards an overall aim of £1.3 billion in annual savings.
Chief executive Warren East said: "This is not a crisis of our making. But it is the crisis that we face and we must deal with it.
"Our airline customers and airframe partners are having to adapt and so must we.
"Being told that there is no longer a job for you is a terrible prospect and it is especially hard when all of us take so much pride in working for Rolls-Royce.
"But we must take difficult decisions to see our business through these unprecedented times."
