Eight Hours Day is celebrated on the second Monday in March in some parts of Australia, including Victoria, Tasmania, and Western Australia. This observance, also known as Labour Day, honors the achievements of the Australian Labour Movement, which began in the 1800s. The movement was initiated by skilled tradesmen who protested against long working hours and demanded an eight-hour workday. Their efforts led to widespread protests across various industries, culminating in the passage of the Eight Hours Act in Victoria, which guaranteed workers the right to an eight-hour workday. The day serves as a commemoration of the collective actions taken by workers to improve their rights and working conditions.
