Union leaders are calling for reassurances after Bombardier announced the loss of 5,000 positions across its business. The Canadian train and aircraft manufacturer employs almost 70,000 people, including 4,000 at Bombardier Aerospace in Northern Ireland and around 3,500 at eight UK sites in its transport division. The cuts, which are expected to save $250M by 2021, were announced in the company's third-quarter results. Bombardier also anticipates revenues of $900M following the sale of non-core assets and monetisation of royalties. The company further predicts revenues of around $16.5bn for the full year and reported $3.6bn in revenue in the last quarter. The GMB union in Belfast and Unite in Derby are seeking talks with senior management at Bombardier following the announcement. Unite's Paresh Patel said: 'Unite will be seeking an urgent meeting to fully understand the details behind the proposed job losses and how this will affect our members at Derby and in the wider supply chain'. The factory in Derby is highly successful and has secured a number of significant new orders in recent months. The company sold its C series aircraft programme earlier this year and is divesting its turboprop business – the Q400 programme – and related training business.
