Most of the staff I take on are part timers, they want 16 hrs per week max so it doesn't effect their benefits 
I know someone who has been unemployed for years, he told me he would need to be paid over 20k a year to make it worth his while working because of what he would lose in government payments
If you have found some good workers from this scheme you're lucky, have any stayed beyond the 16 weeks yet?
The problem why people need 20k is that when they had a job they were living to that or above that standard.
They are commited to a mortgage etc
You can get your rent made up if you take a low paid job but not your mortgage.
Once you start work perhaps your insurance policy stops paying.
It becomes a catch 22 situation . With 100k plus mortgages the situation is getting harder.
So what should people do on loosing a job.
Sell Family home, move into rented accomodation., then they are in a position to take a job at £6 an hour.
