Tata Steel Europe has said it had begun talks with its workers on a “transformation programme” that involves up to 3,000 job cuts.
However the announcement drew an angry response from union leaders, who said the plan needed to be revised.
Tata Steel announced restructuring plans earlier in November, in a bid to boost profitability. The company said it was planning up to 1,600 cuts in the Netherlands, 1,000 in Britain and 350 elsewhere.
Further talks are planned over the coming weeks.
