Angela Neville was an advisor at the Job Centre, but quit after being frustrated by the way things were being run.
She has since written a play about her experiences there and pinpointed the moment when she realised there was a problem with the way benefits were being distributed - when she was forced to sanction a man that was on his death bed.
Speaking to Shelagh Fogarty, Ms Neville told when she realised it was now a target-driven culture, rather than person driven, saying: "Towards the end of 2012, we were given a list of customers to call in or to send immediately to the Work Programme.
"That was the government's programme for customers on job-seekers, ESA, all the different types of benefits.
"As advisors, you do form bonds with customers, you have relationships and that helps you support them.
"I had a particular customer, I said he was in hospital, not expected to live.
"I was told to call him and if he didn't attend or respond, he would probably face a sanction.
"As he would probably be dead, this would be tricky, I thought, and I refused to actually do it."
