Civilian forced laborers from Poland and the Soviet Union were subject to strict rules that limited their freedom of movement. Until December 1942, Soviet civilian laborers in particular were only allowed to leave their communal accommodation in order to go to work. This is indicated by the stamp on the labor cards of Soviet civilian laborers. This information is already preprinted on other labor cards. Polish civilian laborers were increasingly allowed to move around more freely, but they were not permitted to leave the local areas or cities in which they were forced to work. There is often a stamp on their labor cards indicating the places they were not permitted to leave.
