In November 1919, the dockworkers went on strike over bad management practices, low wages compared to a higher cost of living. Strikebreakers were brought in to keep a minimum of goods moving through the ports. On 1 December 1919, the striking dockworkers rushed the harbour and chased off the strikebreakers. They then proceeded to march on the government buildings in Port of Spain. Other unions and workers, many with the same grievances, joined the dock worker's strike making it a General Strike. Violence broke out and was only put down with help from the sailors of British Naval ship . The unity brought upon by the strike was the first time of cooperation between the various ethnic groups of the time. Historian Brinsley Samaroo says that the 1919 strikes "seem to indicate that there was a growing class consciousness after the war and this transcended racial feelings at times."
