In summary, these were actually Tory plans to cut costs, which were described as helping disabled people into work. Internal documents show cost-cutting was the actual intention all along, but Labour tried to block publication of those documents (in a legal way they had a right to try, to be clear).
Labour is now conducting its own review, and may or may not go through with the plans as stated in those documents.
Yeah, unfortunately they forget some facts.
Unless a disabled person has a desirable skill. (in such cases, they are likely already working)
Any company will see hiring disabled as more expensive and less desirable, than non-disabled (or more honestly, less disabled). Although obviously they are never likely to admit it.
Disabled people often know this. This can lead to huge mental health issues. Where disabled people are forced to diminish how their ability affects them during interviews etc.
Honestly, if a person has no high demand professional skill. Being forced to hunt for work where employees are clearly faking a desire or forced to hire you. Can have a really negative effect on the health of the people involved.
