Nearly 1,000 jobs are to be axed at Bombardier Aerospace factories in Northern Ireland.
A total of 975 staff are losing their jobs, with 310 permanent staff and all 665 agency staff being made redundant.
The company said in a statement: “We deeply regret the impact this will have on those affected and their families.
“Unfortunately, however, the force of this global recession is unprecedented, market conditions have worsened, and Bombardier is revising downwards most of its aircraft production rates and implementing measures to meet challenges facing the whole aviation industry.
“We need to do all we can to protect the business now so that when we come out of the recession we will be in a strong position.”
This latest manpower reduction is in addition to the 300 layoffs announced in February. At that time, the company said that permanent staff would not be affected.
The company said it expected redundancies among permanent staff to be achieved through voluntary means.
A further 95 workers are to be made redundant at County Antrim engineering firm FG Wilson, in addition to the 250 jobs it axed in January.
Meanwhile, construction firm Mann has fallen into administration, with the loss of 120 jobs.
