Labour Day, also known as 'May Day' or International Workers' Day, is celebrated in Morocco every year on the 1st of May. This holiday serves as an annual national tribute to the valuable contributions and achievements of the country's working class. As an important holiday in Morocco, businesses, schools, and government offices usually close for the day in recognition of the hard work of employees and labourers.

The holiday is observed with various activities throughout the country. Labour unions organize rallies and demonstrations to promote workers' rights, such as fair wages, reasonable working hours, and safe working conditions. Parades and other public gatherings are common, often with speeches encouraging solidarity among the workforce. Several labour and trade union representatives use this day to address issues concerning labour laws and policies.

Despite being a day off for most workers, Labour Day in Morocco also serves as a time for reflection on the conditions of all workers, particularly those who face hardships and exploitation. The holiday advocates for workers' rights and creates awareness on the importance of protecting these rights. As such, Labour Day in Morocco is not just a day of celebration, but also a moment for policy review and pushing for reforms in the labour sector.
