Labour Day, also recognized as International Workers' Day commemorates the working class and laborers in Angola. This holiday is observed annually on May 1st allowing the people to remember the struggles of the workers and their rights, reflective of the global labor rights movement. Like many nations, Angola recognizes this day as a public holiday, reminiscent of the significant improvements in working conditions and employee rights realized over time.

The origin of Labour Day in Angola, like most countries, originates from the 1886 Haymarket affair in the United States. Originally a strike for better working conditions and an eight-hour workday, it eventually spiraled into a violent confrontation. Commemorating this event, many countries including Angola, celebrate Labour Day in recognition of the rights of workers and the importance of their labor to society.

In Angola, Labour Day is celebrated with a variety of activities. Many businesses close for the day, allowing workers to rest. Labor unions often organize meetings and demonstrations to call attention to workers' rights and promote solidarity among workers. There are also numerous cultural and social events held throughout the country, such as music concerts and family gatherings. Despite the serious nature of its origins, today it is often seen as a day of rest, celebration, and reflection for workers and their contribution to society.
