Over 1,000 former staff of the Coventry tractor manufacturer Massey Ferguson are to appeal to the House of Lords over a court decision that allowed US parent company Agco to reduce their retirement payments as if they'd retired early - even though the factory was shut down by its owners.
The Court of Appeal had previously ruled that the firm could reduce the pensions of workers.
That ruling overturned a High Court decision in December last year which said the workers should get a full pension because they were effectively being made redundant.
