Bloody Thursday Commemoration is observed worldwide every year on July 5 to honor the 1934 West Coast Waterfront Strike, a significant labor movement event. This remembrance day is organized by the International Longshore and Warehouse Union (ILWU) and involves memorial ceremonies to pay tribute to those who lost their lives during the strike, particularly Howard Sperry and Nicholas Bordoise, who were killed during violent clashes with police on that day. The strike began on May 9, 1934, when longshoremen across the West Coast walked out in protest of poor working conditions, leading to a violent confrontation with law enforcement on July 5, which became known as Bloody Thursday. The aftermath of these events spurred a general strike involving over 150,000 workers, lasting four days, and ultimately contributed to the formation of the ILWU. The ceremonies not only remember the fallen but also celebrate the achievements of the labor movement since the strike.
