Cause

Workers from multiple ethnicities and unions, including the International Longshoremen's and Warehousemen's Union, united to challenge the Inter-Island Steam Navigation Company. Led by Harry Kamoku, they demanded equal wages with West Coast workers and union shop recognition. Strikes began on 4 February 1938 after longstanding labor grievances went unresolved.

Event

On 1 August 1938, approximately 200 multiethnic workers gathered at Hilo Harbor to protest the arrival of the SS Waialeale. When they refused orders to disband, more than 70 police officers deployed tear gas, fire hoses, and riot guns against the unarmed crowd, wounding 50 protesters in what became known as the Hilo Massacre or Bloody Monday.

Consequence

Fifty protesters were injured and required hospitalization, though no deaths were recorded. The violent suppression of the multiethnic, multi-union coalition drew public attention to labor conditions in Hawaii and the use of force against workers peacefully exercising their right to protest, contributing to the broader labor rights movement in the territory.
