Thousands of workers representing more than 200 unions marched along Fifth Avenue in Manhattan Saturday in the country's oldest Labor Day parade.

The theme for this year's parade was "All Workers, Many Voices, One Fight," which organizers said represented the unity workers from diverse backgrounds experience in a union.

Organizers also said the "one fight" referred to a union's "shared commitment to advocating for better conditions and fair treatment."

Gov. Kathy Hochul marked the celebration Saturday by signing a slate of worker-related bills, including the Retail Worker Safety Act, which requires retail employers to provide training and information to employees to prevent workplace violence.

"As retail workers face hostile customers and those seeking to commit retail theft, they need the basic tools to deescalate situations and seek help," Assemblymember Karines Reyes, who represents District 87 in the Bronx and introduced the bill alongside State Sen. Jessica Ramos, said. "This landmark legislation will guarantee a critical part of New York's essential workforce, retail workers, with the necessary protections to create safer work environments."

Other bills focused on payroll transparency for contractors and subcontractors working on covered public projects and the expansion of civil service workers' eligibility for advancement.

The country's first Labor Day celebration took place in Union Square on Sept. 5, 1882, when around 10,000 workers marched in a parade organized by the Central Labor Union and the Knights of Labor.

The annual Labor Day Parade typically takes place on the first Saturday after Labor Day, as the West Indian American Day Parade is held on Labor Day itself.
