This is absolutely appalling not to mention dumb..
So this means this woman may have to claim Employment Support Allowance and that means she would eventually be sent to a Work Capability Assessment where she might get wrongly found fit for work.
And then she’d have to claim Job Seekers Allowance and then because of her illness she might not be able to look for work and she’d be sanctioned for not doing so.
This is the stupidity that this ridiculous and punitive system creates. Utter utter disgrace.
