Volteface (Vintage Paperback) by Mark Adlard

The executives have regained power; the revolt of the citizens is over. The executives can resume their luxurious and cultured existence, their peace punctuated only by sexual adventuring in the enclosed corridors of Tcity, and the minimum effort needed to control the vast automated industrial complex. But mental and physical illness is on the increase in Tcity; schizophrenia reappears, and groups of citizens roam from bar to bar till they can walk no longer, or indulge in bizarre and pointless obsessions. In a bid to combat the problem, the executives introduce a startling concept into the deadly claustrophobia of Tcity - work.
