Most disabled workers laid off after the closure of Remploy factories have not found another job a year after they shut, according to a new report.

The GMB union said only one in four ex-Remploy staff were in work, and many of those were on shorter hours and less pay.

In a report marking the first anniversary today of the end of the closure programme, the GMB said many former workers were now sitting at home "depressed and isolated".

National officer Jerry Nelson said: "It is now one year since the final day of the Remploy factory closures. Over 2,700 disabled workers had their lives destroyed by this Government's callous and thoughtless attack on the disabled workers, who relied on their employment to maintain their sense of independence, working in an environment of protected equality.

"The factories were a sheltered environment and for many of these workers it was their only connection with life outside of their own homes."

A Department for Work and Pensions spokesman said: "Disabled people deserve the same employment choices as everyone else - rather than being consigned to work in segregated and loss-making factories.

"A comprehensive 18-month support package, worth £8 million, was provided for those made redundant.

"Since last year, over 80% of ex-Remploy workers have found jobs or are receiving specialist employment support and training to help them find one."

Kate Green, shadow minister for disabilities, said: "This report shows David Cameron's Government has broken its promise to help former Remploy workers into jobs following the closure of the factories last year. It's typical of a Government that has failed to give disabled people the support they need to find work and fulfil their potential.

"Just one in 20 disabled people have found a job thanks to the failed Work Programme while ministers have cut the number of specialist disability employment advisers in Jobcentres by 20%."
