Five of the largest labor union conventions in the United States take place this summer, including the AFL-CIO, the Teamsters and the UAW.
That is not a coincidence. It is a cycle — constitutional conventions, officer elections, and platform-setting gatherings that collectively define union strategy for the next couple of years. When you add them up, the organizations meeting this summer represent well over 20 million workers and likely the same number of strongly worded resolutions will be discussed.
Convention season is intelligence work for employer-side practitioners. What unions resolve to do, who they elect, and what they fight about on the floor provide clues to where organizing is headed, which industries are likely targets, and how aggressive the posture on issues like automation and AI will be at the bargaining table. Pay attention now, or you might read about it in a demand letter later.
AFL-CIO — Minneapolis, June 7-11
Liz Shuler and Fred Redmond ran unopposed for second terms. No challengers emerged despite multiple appeals from the floor — a sign of either deep unity or a room that knew better than to try. Shuler set the tone fast: two million new union members over the next five years, doubling the previous goal they hit in three years instead of ten. Whether you believe the number or not, they believe the number.
The SEIU’s return to the AFL-CIO after more than two decades away is the structural story underneath the headline. That reunion consolidates significant healthcare and property services organizing capacity under the federation umbrella. Two million workers just got a bigger tent.
The agenda runs through Wednesday: AI, immigration enforcement, and 2026 midterm mobilization. The federation plans to deploy 50,000 trained election protectors to polling places where ICE activity is anticipated. They are not playing small ball.
What it means for you: The organizing target is aspirational. The infrastructure behind it is not. If your sector has been quiet, enjoy it while it lasts. The AI panels deserve your attention — how labor frames automation at convention this week could become what your next negotiating committee puts on the table or drives potential organizing.
UAW — Detroit, June 15-18
Shawn Fain is running for re-election on a “Stand Up Slate” of 13 candidates at the 39th Constitutional Convention. He faces at least four challengers, including Brian Keller, a Stellantis worker who built a social media following by being loudly unhappy with Fain, and Will Lehman, a Mack Trucks worker who ran against Fain before and apparently enjoyed it.
The convention nominates but does not elect. The actual vote goes to roughly 400,000 active members and 600,000 retirees later this year. Detroit is where the campaigns launch, not where they land.
Fain’s tenure has been eventful. The 2023 Stand Up Strike. An internal war with former Secretary-Treasurer Margaret Mock that got ugly fast. Organizing promises in the South is still a work in progress. The convention floor will debate strike pay, dues structures, and how the tariff environment is affecting the industry that keeps this union alive.
What it means for you: A union mid-election cycle is a union making promises it must keep. Watch what Fain and his challengers commit to on organizing — those become field priorities. What gets said about non-union Southern facilities in Detroit this week is a preview of who might show up at your gate next year.
Teamsters — Las Vegas, June 14-18
The most volatile convention of the summer, and not in a good way if you need predictability from your Teamsters relationships.
Sean O’Brien wants a second term. His first featured the 2023 UPS contract, a turn at the Republican National Convention, and relationships with Josh Hawley and the Trump administration that split his own coalition. A challenger slate called “Fearless,” led by Richard Hooker Jr., who would be the first Black General President in Teamsters history, is trying to get on the ballot. Hooker needs 5% of the delegates, roughly 80 votes. O’Brien’s allies are working the floor to make sure he never gets there.
The fight over the nomination threshold itself is a story. If Hooker clears it, a contested mail ballot election runs through October and November — months of internal warfare across one of the most geographically dispersed unions in the country.
What it means for you: The Teamsters touch freight, logistics, food and beverage, healthcare, and the public sector. O’Brien’s re-election means continuity. A contested race means distraction, unpredictability, and local leadership reading the room for which way the wind is blowing. Neither outcome produces a quieter labor environment.
AFT — Late July
The American Federation of Teachers (AFT) holds its 89th biennial convention in Washington this month. Randi Weingarten leads 1.7 million members across K-12 education, higher education, and healthcare. Those three sectors matter here because the AFT has been the loudest institutional union voice on the issues hitting all three right now: immigration enforcement on campuses, attacks on academic freedom, and federal workforce cuts bleeding into state and local public employment. The convention will put forth resolutions behind that posture.
AFSCME — Chicago, August 17-21
Lee Saunders leads the American Federation of State, County and Municipal Employees (AFSCME) into an uncontested convention with 1.6 million public sector members and a lot of anger about the dismantling of the federal workforce that needs to be channeled somewhere. The central question is what the current administration’s assault on federal employment means for organizing density at the state and local level.
The Through-Line
Every one of these conventions operates against the same backdrop: a federal administration showing a mixed response to the interests of organized labor, an NLRB running well behind due to a backlog capacity, and an organizing environment that has produced real gains in a few sectors while overall density hovers near historic lows.
Unions use conventions to set strategy, build internal consensus, and send signals simultaneously. The resolutions passed, the candidates elevated, and the fights on the floor are all data. Convention season is when that data is loudest and cheapest to collect.
