A trades hall is a building where trade unions meet together, or work from cooperatively, as a local representative organisation, known as a labour council or trades hall council.[1] The term is commonly used in England, New Zealand, Scotland and Australia. They are sometimes called a union hall, or labour temple in North America (see, for instance, Finnish Labour Temple, Labor Temple Building, Union Hall (Danforth, Maine), etc.)
They are sometimes colloquially called "the worker's parliament".
