Acknowledgments
A special thanks goes to the Cornell-ILR School and University of Illinois LER School for funding our project and the entire Labor Action Tracker research team for putting in the hours to document strike activity. We would also like to thank Betsy Wiggers, Dave Yantorno, Mary Catt, Adam Allington, Jeff Amaral, David DeMello, and Nell Madigan for their excellent design and promotion of our report.
Introduction
With sustained work stoppages in several sectors amidst a presidential election, 2024 marked another important year for the U.S. labor movement. We are excited to release the fourth Labor Action Tracker Annual Report, in which we present key findings from our 2024 work stoppage data.
Increasing considerably over the past three years, strikes are an important tool for workplace and labor activism. Since funding cuts by the Reagan administration in the early-1980s, the Bureau of Labor Statistics (BLS) has only documented work stoppages involving 1,000 or more workers that last at least an entire shift. By only recording large work stoppages, official data sources exclude the vast majority of strike activity, posing issues for policymakers, practitioners, and scholars in determining the extent of workplace conflict across the country. In this report, we follow the lead of the BLS and document work stoppages, which include both strikes and lockouts. You can follow our project and view our monthly reports of strike activity on X (formerly Twitter) @ILRLaborAction and Bluesky @Laboraction.bsky.social.
Methodology
This report is based on data we collected on strikes and lockouts in 2024. Detailed information on our project’s methodology can be found here. Further details specific to the methodology for this report can be found throughout this document. We generate all our data on strikes from several public sources, including existing work stoppage databases, news articles, and social media posts. We follow rigorous verification protocols to ensure that a strike did in fact occur and to collect data on several related variables, including, but not limited to, the size, duration, industry, and demands of a strike. We link to the sources used to generate data on each strike on our site’s interactive map. We also collect data on labor protests but only provide summaries of work stoppages in this report because our count of protests is less comprehensive. In light of our rigorous protocols, we may underestimate the total amount of work stoppages as we cannot include events that do not have adequate verifiable information.
Updated 2023 findings
Our 2023 data now include 471 work stoppages. We added a one-day strike in Puerto Rico that brought the total up by 1 strike. We do not intend to further update 2023 findings.
Key findings from 2024
We documented 359 work stoppages (356 strikes and 3 lockouts) involving approximately 293,500 workers in 2024. These work stoppages resulted in 5,328,345.5 strike days.
The number of work stoppages in 2024 continued to exceed 2021 levels but were not as many as in 2022 or 2023. The number of work stoppages decreased by 23.8% in 2024 compared to 2023 and the approximate number of workers also decreased by 45.5%. The decline in the total number of strikes is overwhelmingly due to the decline in the number of one-day strikes, which is attributable in large part to the decrease in the number of strikes by Starbucks Workers United in 2024 as compared to 2022 and 2023. The five largest strikes of the year involved union members at Boeing, California State University, University of California, University of California Health, and the United States Maritime Alliance, totaling a little over half (~152,300) of all the workers engaged in strikes this year.

Some notable trends are emerging over the last four years from our data. In 2024, workers’ top three demands in work stoppages were better pay, improved health and safety and increased staffing, which remained the same the last two years. Also like in 2023, accommodation and food services still accounted for the largest number of work stoppages by any industry (23.6%), though less than the approximately one-third of all work stoppages this industry accounted for in 2022 and 2023. Third, unlike in 2023, the vast majority of striking workers came from educational services (32.7%) and the highest number of strike days from manufacturing (40%). Fourth, there was a slight increase in the percentage of work stoppages organized by nonunionized workers (24.8%) as compared to 2023. Fifth, in terms of region, the West accounted for more work stoppages (40.7%) and the overwhelming majority of workers involved in stoppages (66.8%) compared to any other region in the United States.
Overall, the total number of work stoppages, approximate number of workers and strike days did not reach 2023 levels, but the number of stoppages, workers involved, and strike days in 2024 exceeds those of 2021 and the number of workers involved, and strike days exceeds those of 2022.


Number of work stoppages and approximate number of workers involved in stoppages per month
In 2024, approximately 293,500 workers were involved in 359 work stoppages (356 strikes and 3 lockouts) totalling 5,328,345.5 strike days. The number of work stoppages stayed relatively consistent over the year before increasing considerably between August and September. The number of workers on strike spiked in September.


Labor action by industry
There were more work stoppages in the accommodation and food services industry than in any other industry, accounting for 23.6% of all work stoppages. Educational services involved the greatest number of workers (32.7%). About two fifths of all strike days were accounted for by the manufacturing industry.

Labor action by duration
About three fifths of all strikes in 2024 lasted less than 5 days. However, close to 18% of all workers who were striking were on the picket line for more than a month.

Labor action by size
A little over a third of all work stoppages involved fewer than 50 workers. Of the 293,489 workers who were involved in the work stoppages, a vast majority engaged in labor actions with more than 1000 workers.

Labor action by demand
The most common demands in 2024 were pay, improved health and safety and increased staffing.

Labor action by unionization status
Three fourths of work stoppages this year involved unionized workers (75.2%) while just around a fourth of all work stoppages were led by non-union workers (24.8%). Unionized workers comprised the vast majority of workers involved in work stoppages (98.4%) and strike days (99.3%) respectively.

Labor action by authorization status
A vast majority of all unionized strikes (92.8%) were authorized by a union compared to 4.8% that were unauthorized and 2.2% that were unknown. Authorized strikes overwhelmingly accounted for the number of workers (99.4%) and strike days (99.96%).

Labor action by region
Most work stoppages happened in the West as compared to other regions. The majority of workers who were on strike also came from the West. Similar to 2023, more work stoppages were found in the Midwest than the South.
