Zivilarbeiter (civilian worker) refers primarily to ethnic Polish residents from the General Government (Nazi-occupied central Poland), used during World War II as forced laborers in the Third Reich.
The residents of occupied Poland were conscripted on the basis of the so-called Polish decrees (Polenerlasse), and were subject to discriminatory regulation.
Compared to German workers or foreign workers from neutral and German-allied countries (Gastarbeitnehmer), Polish Zivilarbeiters received lower wages and were not allowed to use public conveniences (such as public transport) or visit many public spaces and businesses (for example they were not allowed to attend German church services, visit swimming pools or restaurants); they had to work longer hours than Germans; they received smaller food rations; they were subject to a curfew; they often were denied holidays and had to work seven days a week; could not enter a marriage without permission; possess money or objects of value.
[2] Poles from territories taken over after the German invasion of the Soviet Union and not included in the General Government (see Kresy) were treated as Ostarbeiters.
[3] The history of Polish Zivilarbeiters dates back to October 1939, when German authorities issued a decree, which introduced mandatory work system for all residents aged 18 to 60.
