Falling export demand and commodity prices placed massive downward pressures on wages, particularly in industries such as coal mining. Due to falling prices, bosses were unable to pay the wages that workers wanted. The result was a series of crippling strikes in many sectors of the economy in the late 1920s. Coal miners' strikes in the winter of 1929 brought much of the economy to its knees. A riot at a picket line in the Hunter Region mining town of Rothbury saw police shoot one teenage coal miner dead.
