Much longer than that...I was a PwC senior IT management consultant from 1989-1994 and I did a lot of puclic sector work at a fee of >£1,000 + expenses per day.
I met my wife, Caroline, in 1990 on a job at London Borough of Tower Hamlets implementing the Local Government Act 1988 (which extended CCT to blue-collar services, such as refuse collection and ground maintenance, and white-collar services such as public libraries and arts centre management).
