On May 1, Ukraine celebrates an international holiday - Labor Day, which was originally called the International Workers' Day.
This holiday is celebrated in 142 countries and territories of the world. It commemorates the working protests in Chicago which began on May 1, 1986. On that very day, hundreds of thousands of the biggest working industrial centers in the USA demanded the implementation of the 8 hours working day.
That is why this day is believed to be The Day of the national fight for the rights of the workers.
For the first time, Labor Day was celebrated in 1980 in many countries of the world, in particular in Lviv. The mass demonstrations and protests took place in Vienna, Prague, Krakow, Budapest, Paris, and Milan.
