<P> The One Big Union was an idea in the late 19th and early 20th centuries amongst trade unionists to unite the interests of workers and offer solutions to all labour problems . </P> <P> Unions initially organised as craft or trade unions .

Capitalists could often divide craft and trade unionists along these lines in demarcation disputes .

Hagerty and William Trautmann enumerated two goals: One Big Union needed to "combine the wage - workers in such a way that it can most successfully fight the battles and protect the interests of the workers of today in their struggles for fewer hours of toil, more wages and better conditions," and it also "must offer a final solution of the labor problem--an emancipation from strikes, injunctions, bull - pens, and scabbing of one against the other ." </P> <P> One Big Union was the notional organisational concept, while the IWW's revolutionary industrial unionism was the organizing method by which that concept could be realised .
