The Luxembourg Workers' Union (Luxembourgish: Lëtzebuerger Arbechter-Verband, LAV) was a general union in Luxembourg.
[1][2] The union led a major strike in March 1921, against redundancies, but this was unsuccessful, and also led to the temporary banning of factory councils.
In 1936, it worked with the LCGB to organise a major strike in support of improved pay and collective bargaining.
The following year, the union's left wing split away, to form the Free Luxembourger Workers' Union.
In 1977, it merged with the General Federation of Teachers, to form the Independent Luxembourg Trade Union Confederation.
