According to an expert, a lot of improvement is needed when it comes to testing if disabled or sick people are fit to work and called these tests ‘patchy’.

People who are not capable of working will have to suffer, according to Professor Malcolm Harrington, the man appointed by the Government to review the Work Capability Assessment.

Professor Harrington said, “There are certainly areas where it's still not working. More than 176,000 people who have been judged fit to work go to appeal tribunals each year.”

There have been cases of sick or disabled people being declared fit to work by Government’s Work Capability Assessment and this has been done even when GPs have given this medical advice.

Because of being too unwell to work, in the UK alone about two and a half million people are required to take the test. The Work Capability Assessments is conducted by the contract between the Department of Work and Pensions and Atos Healthcare, this runs to 2015 and is worth a billion pounds.
