I was on the 24th floor ASparks working for the Manpower Services Commission - executive arm of the Dept of Employment. We moved to AT from Windsor House (above Rackhams) in about 1980. I was working on manpower intelligence - preparing ministerial briefing, data and statistical reports about labour supply, demographic analysis etc. I liked working at AT. On the plus side : they were modern, clean open plan offices, great views and very fast lifts. On the negative side: a bit cut off from the shops and a nightmare when it came to fire drills. All those stairs from the 24th floor, very dizzy when you got to the bottom.
So we may have crossed paths, even shared a lift! Viv.
