In one calendar year, there are many public holidays, each significant in its own right and celebrated on various occasions. However, there is one holiday that holds particular significance for salaried workers worldwide: "Labor Day." In this article, we will delve into the history of Labor Day, its origins, and its importance.

Many people are well aware that "International Workers' Day" falls on May 1st every year, and in many countries, this day has been celebrated for a long time. It's commonly referred to as "May Day," and it is considered a beautiful and auspicious occasion, marking the beginning of the agricultural season. Therefore, there are ceremonies and festivities to bless the crops, wishing for abundant growth, flowering, and fruitful harvests, along with the happiness and well-being of the people. This tradition has been passed down through generations and continues to this day.

As industries expanded in Thailand, the demand for labor increased, leading to labor-related issues. Consequently, in the year 1932 (B.E. 2475), Thailand began allocating resources and developing its labor force. This initiative aimed to protect and improve working conditions for laborers, fostering better relationships between employers and employees.

In the year 1956 (B.E. 2499), the Labor Day commemoration committee convened and unanimously agreed to designate May 1st as a day to honor Thai laborers. A letter was then sent to the Prime Minister requesting official recognition of May 1st as National Labor Day. Subsequently, it was officially changed to International Workers' Day, and a royal decree was issued granting employees the right to take a day off on this National Labor Day.

In the year 1957 (B.E. 2500), a royal decree was issued to outline measures to resolve labor disputes, granting employees the right to take a day off on National Labor Day. However, this version of the royal decree had a lifespan of only 18 months before being revoked by Declaration No. 19 of the Revolutionary Council. Subsequently, the Ministry of Interior was authorized to issue regulations regarding labor protection. Additionally, Labor Day was designated as a customary holiday. However, due to the uncertain domestic situation at the time, annual instructions were issued to employers to remind them to allow employees to take the day off on May 1st. In some cases, requests were made to refrain from celebrations for the sake of domestic peace and tranquility.

"International Workers' Day" aims to remind people of the importance of laborers who contribute to the country's economy."

For International Workers' Day, it is not considered a public holiday. Therefore, government offices remain open and provide services as usual on International Workers' Day. Only state enterprises and private organizations may grant leave on this day.
