Which event does Trinidad and Tobago’s Labour Day commemorate on June 19?

Trinidad and Tobago’s Labour Day commemorates the 1937 Butler Riots on June 19.

The holiday honors the oilfield workers’ uprising led by Tubal Uriah Butler. In 1937, workers in the oil-producing areas of southern Trinidad protested poor wages, unsafe conditions, and exploitative labor practices. The unrest spread and became a major challenge to colonial authorities.

June 19 was chosen because it marks the beginning of the 1937 disturbances. The day became a public holiday in Trinidad and Tobago in 1973, making it one of the country’s most important commemorations of organized labor and workers’ rights.

The event is often called the Butler Riots, although it formed part of a broader labor uprising. It is distinct from the 1970 Black Power Revolution, another major episode in the country’s modern political history.
