May 1st has been considered a national holiday in Brazil since 1949 and alludes to a strike that took place in the US city of Chicago in 1886. This year, the date will take place on Thursday.
Labor Day entered the official calendar from a law approved by the Senate and the House, signed by President Arthur Bernardes in 1924. According to the Federal Senate, the holiday was born with the objective of celebrating the “universal fraternity of working classes” and “labor martyrs”.
