Scunthorpe-based British Steel has announced plans to cut 400 jobs.
The steel giant, which has its headquarters in the North Lincolnshire town, has said it is undergoing a "streamlining process to ensure the long-term growth of the business".
The company is proposing a reduction of 400 managerial, professional and administrative roles at its operations in the UK, Ireland, France and the Netherlands.
It has not yet been announced how the proposals affect jobs at the Scunthorpe works.
British Steel bosses say other steps involved in the streamlining process include continuing to improve manufacturing performance and increasing turnover through strong sales.
