Answer:
The industrial workers of the world (IWW) was a labour union founded in 1905. Its goal was to organise all of the workers into single union for abolishing the capitalist system. IWW focused on the unskilled workers and made efforts for organising the groups that were overlooked and ignored by other unions such as women, immigrants and African- Americans. It was at its height and strongest in the 1910's, mostly popular among the Finns and Italians. Its symbol was black cat and all its members were given a red membership card, they were called Wobbles.
