Labour Day in Trinidad and Tobago was declared an annual national holiday in 1973. It's the anniversary of the day of the Butler Oilfield Riots which took place in 1937.
Trade Unions braved the rains and filled the streets of Fyzabad on Tuesday morning to commemorate Tubal Uriah "Buzz" Butler's work for the improvement of the working class.
Many of the union leaders used the opportunity to express their dissatisfaction with the way workers are currently treated in this country.
