The Central Union of Employees (German: Zentralverband der Angestellten, ZdA) was a trade union representing white collar, private sector workers in Germany.

It affiliated to the General German Trade Union Confederation (ADGB), and by 1920 had 363,521 members.

[1][2][3] In 1921, the ZdA became a founding constituent of the General Federation of Free Employees, leaving the AGDB, but remaining aligned with it through the Social Democratic Party of Germany (SPD).

[4] The union published Der freie Angestellte, initially edited by Paul Lange, and from 1930 by Georg Ucko.

[3][5] In its early years, the union was divided between the leadership, generally SPD supporters, and the "Berlin Opposition", an alliance of Communist Party of Germany and Independent Social Democratic Party of Germany supporters.
