There's no consideration for people who are seriously mentally unwell either.
I have had a brilliant experience when seriously unwell with mental health with Job Centre and DWP - not everyone who works for the DWP is an asshole. I was treated with care, compassion, given support, advice and a lot of support. My case worker, assessor, job coach were all excellent.
The only people who were not were the Debt service part who said I owed money but still cannot explain why. I am paying it back 50 pounds per month and it is being investigated now - but this was the only part I have found to not be up to standard.
If you are seriously unwell then you don't have to go to appointments in my experience - my job coach filled in the exemption - maybe some don't know about this?
