Labour Day Description
International Workers' Day is a national public holiday in Portugal. Trade union marches and rallies are held in major cities, particularly in Lisbon and Porto, emphasizing workers' rights and social justice. The day traces its Portuguese origins to the Carnation Revolution of 1974, which first recognized this holiday. Public offices, banks, and most businesses close. Many Portuguese use the day for family picnics, often including grilled sardines, or trips to the countryside. Local festivals and open-air concerts also feature in smaller towns.
