This just shows how evil the DWP are, they lack understanding, empathy, common sense and many more.
People want to show their best and get penalised for doing so.
People have good and bad days, so how can one assessment decide how many good or bad days there are. Do they take into account pain thresholds and any other aspects.
From these reports it appears their first priority is to turn down claims, perhaps there is a target, or a reward for doing so.
Many people will give up or not appeal because they are so depressed by the process. Unfortunately this is but one process the disabled, the poor, the vulnerable, etc have to go through and all are demoralising be they Government, Local Authority or Health (Continuing Health Care).
It is as though the system is against them and more likely it is, this is not welfare, but punishment.
