The General Dutch Association for Trade and Office Clerks and Travelling Salesmen (Dutch: Algemene Nederlandse Bond voor Handels- en Kantoorbedienden en Handelsreizigers, often known as Mercurius, was a trade union representing white collar workers in the Netherlands.
The union was established on 1 October 1940, during World War II.
The Nazi occupiers merged the General Dutch Union of Trade and Office Workers, an affiliate of the Dutch Confederation of Trade Unions (NVV), with the independent Mercurius union.
However, in 1952, when the NVV decided to reorganise its affiliates as industrial unions, it lost many members to unions representing their industries.
[1] It took the official name General Union Mercurius, Industrial Union for Trade, Banking and Insurance, and Free Professions.
