Handbetrieb (Manual Operation) is a play by the Polish-born writer Paul Grazik from 1976, which was premiered in the Volksbühne in the same year. The piece shows the contradictory nature of the political and economic goals with outdated machines, which makes it impossible to achieve these goals. Through their own fears of existence, the workers are persuaded to continuously improve the results towards those responsible. When a worker plagued by remorse reveals the grievances, the collective, which is only held together by deceptions, disintegrates. (Source: Metzler Lexikon DDR-Literatur)
