Denver Art Museum's first-ever union contract officially took effect on August 5, ending a two-year campaign that began with a March 2024 election victory and included 13 unfair labor practice complaints filed against museum management along the way. The three-year agreement, ratified by members in June, guarantees equitable pay structures, just-cause job protections, expanded parental leave, increased sick leave, and updated health and safety policies for the roughly 200 to 250 workers it covers.
The union, now known as AFSCME Local 5280, first announced its intention to organize in January 2024, and Denver Art Museum management declined to voluntarily recognize the effort, saying at the time that a National Labor Relations Board secret-ballot election was necessary so every eligible employee could have a voice, according to The Colorado Sun. Workers won that election on March 7, 2024, by a 120–59 vote, a 67 percent majority, establishing what is considered the first unionized art museum workforce in Colorado, as reported by Westword.
A Campaign Marked By Complaints And Pushback
The road between that election win and a signed contract was not smooth. AFSCME New Mexico and Colorado Council 18 filed 13 unfair labor practice complaints against museum leadership during the organizing drive, alleging tactics that included altering the employee handbook, holding mandatory meetings that falsely told lead staff they were ineligible to unionize, and questioning employees about their social media organizing activity, according to Southwest Contemporary. Denver Art Museum settled the matter earlier this year without admitting wrongdoing, telling Westword the NLRB complaint concerned workplace policy language and that it agreed to rescind an employee confidentiality rule as part of the resolution.
The museum maintained throughout that it respected employees' legal right to organize and choose union representation, and said it pledged not to disrupt the organizing process. Denver Art Museum described the eventual bargaining process as thorough, detailed and professional, and said it engaged in good-faith negotiations with the union, per the same Westword report. Trudy Lovato, cited in that reporting, confirmed workers won the union election that set the whole process in motion.
Workers Describe Stalled Pay And Advancement
Behind the statistics were individual accounts of frustration inside the museum's departments. Kit Bernal worked in the museum's sales-and-services department starting in 2021 before moving into a curatorial assistant role in 2022, and told Westword she made no money and had few opportunities to advance. More broadly, workers reported difficulty advancing in their positions along with financial struggles and workplace safety issues, though the union has said staff is not necessarily dissatisfied with the museum simply because they organized.
Denver Art Museum, located in Denver and home to a collection encompassing more than 80,000 works across a campus of over 400,000 square feet, employed more than 440 staff and relied on over 300 volunteers as of 2024, according to the Colorado Sun. The bargaining unit itself spans 62 job classifications, including conservators, gallery hosts, sales associates, and curatorial assistants. The museum has said it will focus on welcoming visitors, supporting the cultural community, and maintaining a positive workplace, adding that staff passion for its mission is the institution's greatest strength.
Part Of A Broader Colorado And National Wave
The Denver Art Museum campaign did not unfold in isolation. On the same day in March 2024 that museum workers voted to unionize, Jefferson County Public Library staff also voted for union representation under AFSCME, part of a wave encouraged by Colorado's public-sector bargaining legislation that saw more than 1,100 Colorado public workers join AFSCME that year, according to Labor Press. Jefferson County's 350 library workers went on to ratify their own contract in March 2026, securing a 7 percent across-the-board raise and eliminating at-will employment, per AFSCME.
Nationally, the union's Cultural Workers United campaign represented more than 50,000 workers across cultural institutions as of August 2025, including roughly 10,000 museum staff at over 100 institutions such as the Metropolitan Museum of Art and the American Museum of Natural History, AFSCME reports. The American Federation of State, County & Municipal Employees is an AFL-CIO branch, and organizers behind the Denver Art Museum union have said they hope their win inspires other cultural institutions to organize and that they hope to share best practices and resources with peer museums.
Denver's campaign also mirrors a pattern playing out at Seattle's museum and other institutions, as per Hoodline, where staff at the Tacoma Art Museum, Detroit Institute of Arts, and Institute of Contemporary Art/Boston have pushed for higher entry-level pay and more transparent decision-making. Entry-level museum wages have historically hovered near minimum wage, a backdrop that helps explain why organizers in Denver framed their union as seeking better wages and treatment for cultural workers broadly, not just at one institution.
