If the plans com to fruition I’m not sure it’s really meant to help anyone at all, rather just a way to hand out some more public money to a well-connected contractor.

To properly bring down long term sickness rates would mean fixing the NHS and greatly reforming regulations on employment and working conditions. Brining back opportunities for adult education would also help, I’ve known plenty of people who had to leave a particular career due to health issues, but could pursue many others if they had access to retraining.
