The struggle of the working class and the organised activity of the trade union movement have substantially determined the course of Guyana’s history. While Guyana was not unique, it led the way with the formation in 1922 by Hubert Nathaniel Critchlow of the BGLU (British Guiana Labour Union), the first trade union registered in the British Empire in 1922.
Several trade unions were formed subsequently, among them the TWU (Transport Workers Union). Registered in 1938, it had become by the mid 1940s one of the largest and most militant. The Teare Strike by the TWU in 1947 was called to protest the suspension of two workers for trade union activity. It lasted for two weeks, crippled the movement of people and goods in the country and succeeded in its objective of obtaining a commitment that the contract of Colonel Teare, who was the authoritarian British General Manager of the Transport and Harbours Department, would not be renewed after it expired, an unheard of concession at that time. This strike most likely energised sugar workers and the GIWU (Guyana Industrial Workers Union), the predecessor to GAWU, into renewed struggle the following year, leading to the tragic loss of life at Enmore by the Martyrs.
