Labour Day in Belize, observed on May 1st each year, is a public holiday that pays tribute to the strength, dedication, and contribution of the working class. Belize joins many other countries worldwide in celebrating this day, also known as International Workers' Day. The holiday's origins can be traced back to the late 19th century labor movement's rights battles, particularly the eight-hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest.

Labour Day in Belize is typically marked by various events and activities organized by trade unions and workers' groups. These activities often include marches, rallies, and meetings where workers' rights and labour issues are discussed. Such events provide an important platform for workers to voice their concerns and demands for better working conditions, fair wages, and respect for their rights. Trade unions in Belize have been instrumental in shaping and improving labour law, ensuring workers' rights and benefits are protected.

Aside from the activism and important discussions, Labour Day also signifies a day of rest for many. The day is a public holiday, so businesses are closed, and people get the day off work. Many Belizeans use this day to relax and spend time with family and friends. Parades and public gatherings are also a common sight, often featuring music, dance, and food, reflecting the rich culture of Belize and the resilience of its people. In all ways, Labour Day serves to highlight the significant role of the workforce in the growth and prosperity of Belize.
