One of Northern Ireland's main aerospace companies, Bombardier, is to cut almost 400 jobs.
The Canadian firm produces wings and other parts in Belfast and the cuts are part of a major global restructuring which the firm has previously said will hit 1,800 posts world wide.
It is one of Northern Ireland's biggest employers with about 5,000 permanent employees and approximately 1,000 temporary and contract staff working at the east Belfast base. The firm will be ending 300 temporary and contract jobs and is seeking 90 redundancies from its permanent workforce.
"It is right across the company, all areas of the company will be affected," a spokeswoman said. "We regret to confirm that up to 90 Bombardier employees in Northern Ireland are at risk of redundancy.
"What we will be doing is lodging a formal redundancy notice with government and a 30-day consultancy period will be held. That gives us an opportunity to explore means to mitigate compulsory redundancy. In addition we will be releasing up to 300 contractors, temporary workers and members of our complementary workforce."
Over the past four years, Bombardier has increased its total Northern Ireland workforce by more than 1,200, primarily through temporary contract jobs, the spokeswoman for the company in Belfast added.
The Belfast centre will become part of a new section within Bombardier specialising in the supply and development of large structures such as wings in composite plastics or metal.
The spokeswoman added: "That will allow us to be more flexible in terms of responding to customer needs."
Half of the 300 temporary employees who are affected work on the shop floor making the products.
Bombardier has faced a series of delays in its work surrounding the new C-series jet project, which is an expansion into the 100 to 149 seat market.
