Many Spanish workers became involved in illegal strikes during the 1960s. The majority of strikes focused on better pay and conditions rather than demands for political reform. Large-scale strikes first occurred in the Basque region and Barcelona in 1962. Illegal Worker Commissions were organised to protest against poor pay and by the late 1960s, strikes became more frequent. In 1968, it is estimated that over 1.1 million workers went on strike due to low wages.
