Profile of Private Nonprofit Art Museum Unions

In this section, we examine the characteristics of all private nonprofit art museum unions in our dataset. For information on the public and university art museum unions, please visit the spotlight. A union is defined as a group of workers who join together to collectively bargain for a shared contract. Since the terms union, unit, and local, can be defined and applied differently depending on context—and may often be used interchangeably in everyday conversation despite nuanced legal differences—we chose to distinguish unions by separate contracts, even if that differs from how the union in question would describe itself.8 We are actively seeking more information about any union that predates 2019.

Institutional Overview


Regional Distribution9 of Unionized Private Nonprofit Art Museums

There are private nonprofit art museums with unions in every region in the country: Mid-Atlantic (X%), Western (X%), Midwest (X%), New England (X%), Mountain Plains (X%), and Southeast (X%). However, union density does not always reflect the density of museums in a region. For example, the Mid-Atlantic accounts for only 16% of all private nonprofit art museums in the US overall but accounts for X% of the sector’s unions%.10 This discrepancy between the regional densities of museums versus unionized museums opens up questions around other possible explanations, such as regional differences in labor laws.

Operating Budgets of Unionized Private Nonprofit Art Museums

X% of private nonprofit art museums with unions have annual operating budgets of more than $20 million. This statistic is particularly notable in the context of an oft-repeated fear: can the museum afford to have a union?11

Number of Separate Union Contracts at Private Nonprofit Art Museums

Bargaining units often only reflect some of the workers within an art museum. In some cases, there may be more than one union representing different workers within the same museum. X% of private nonprofit art museums have more than one union representing workers.

Union overview


Union Sizes in Private Nonprofit Art Museums

We collected the bargaining unit size (number of members that a union represents) from a variety of sources including the union’s self-reported data, the National Labor Relations Board, Human Resources’ or management’s records, and news articles. Please note that these reports sometimes vary significantly, and the size of a bargaining unit often shifts over time as museums grow, downsize, and/or reorganize their staff. Based on our best estimates, the percentage of art museum unions within each bargaining unit size is as follows: less than 20 members (X%), 20–50 members (X%), 51–100 members (X%), 101–200 members (X%), and more than 200 members (X%).

Parent Union Affiliation of Unions in Private Nonprofit Art Museums

Parent unions United Auto Workers (UAW) 2110 and the American Federation of State, County, and Municipal Employees (AFSCME) represent X% of unionized workers at private nonprofit art museums, but there are many unions who have sought representation elsewhere or have gone independent. (See parent union and parent union acronyms in the Glossary of Terms for more.)

Positions Represented by Private Nonprofit Art Museum Unions

X% of the private nonprofit art museum unions represent workers in the building operations department area.12 This is unsurprising given the longstanding nature of many of the unions representing building operations staff, compared to those in the Administration (X%), Collections (X%), Communications (X%), and Public Engagement (%) department areas. Visit the Unions Index and filter by Unit Composition to view which units represent workers from specific department areas.


  1. ^ The Museum of Fine Arts, Boston (MFA), for example, employs workers who are represented by (1) UAW Local 2110, (2) IUOE Local 877, (3) IBEW Local 103, (4) IUPAT District Council 35, (5) UA Local 51, and (6) UBC Local 327. The five trade unions (#2–6) negotiate a single contract together. MFA also employed security staff who were represented by a longstanding independent union (MISU). As of April 2024 after two years of negotiations, they will remain represented by MISU but are now subcontracted rather than employed directly by the MFA. Therefore, three unions at the MFA are featured in the Index, based on the three different contracts there.
  2. ^ Regions align with the Association of Art Museum Directors’ definitions. They are Southeast (AL, AR, FL, GA, KY, LA, MS, NC, SC, TN, VA, WV, and PR), Mountain Plains (CO, KS, MT, ND, NE, NM, OK, SD, TX, and WY), Western (AK, AZ, CA, HI, ID, NV, OR, UT, and WA), New England (CT, MA, ME, NH, RI, and VT), Mid-Atlantic (DC, DE, MD, NJ, NY, and PA), and Midwest (IA, IL, IN, MI, MN, MO, OH, and WI).
  3. ^ For this data point, we analyzed data from the report by Lisa M. Frehill and Marisa Pelczar, “Data File Documentation: Museum Data Files,” Institute of Museum and Library Services, November 2018, https://www.imls.gov/research-evaluation/data-collection/museum-data-files. We determined the subset “private nonprofit art museums” with the following tags: Art, IRS registered nonprofits, and no academic institution affiliation.

  5. ^ Building operations encompasses art preparation, gardens/grounds, facilities, food services, security, retail and store, exhibitions design, and janitorial work. See department in the Glossary of Terms for the classification of all departments by roles.
