Control Council Law No 22, Works Councils (10 April 1946) was a German labour law drafted in Allied-occupied Germany by the Military Government, to enable organisation of work councils in rebuilding the economy and society after World War Two.
 Work councils, which employees of a firm organised and elected democratically to determine workplace issues, had existed in Germany in various forms since 1889.
 They had been abolished by Adolf Hitler's Nazi party.
 The new Control Council Law No 22 provided a template for democratic German trade unions to reorganise through collective agreements with employers.

 It was passed the day after Germany invaded Poland, and it allowed the government to exercise emergency powers during World War II (known in Ireland as The Emergency), despite the fact that the state was neutral.
