No. As of 2026, Honda's Ohio manufacturing facilities are not unionized. The United Auto Workers have historically sought to organize workers at these sites, but no plant has a certified union contract in place.
Honda in Ohio: facilities and production
Honda operates several key manufacturing sites in Ohio that form a cornerstone of its North American production network. The Marysville Auto Plant, East Liberty Auto Plant, and the Anna Engine Plant have produced a range of Honda models and components for decades, contributing significantly to the state's manufacturing footprint and to Honda's supply chain.
Unionization history and current status
Over the years, the United Auto Workers (UAW) has conducted organizing campaigns at Honda’s Ohio facilities. While the efforts have attracted attention and public discussion about worker representation, none of the Ohio plants has entered into a collective bargaining agreement, and workers are not represented by a labor union on a plant-wide basis. Honda has framed its non-union approach as aiding flexibility and efficiency, whereas labor advocates emphasize the importance of formal worker voice through a bargaining contract.
Marysville Auto Plant
MAP is one of Honda’s largest U.S. production facilities, building several models. It has remained non-union despite organizing efforts by labor groups.
East Liberty Auto Plant
ELAP produces multiple Honda models and has also stayed non-union through various organizing campaigns.
Anna Engine Plant
The Anna Engine Plant supplies engines to Honda’s American operations and operates under the same non-union framework as the other Ohio facilities, with no union contract in place.
Implications for workers and management
Without a formal union, wages, benefits, and working conditions are typically negotiated through company channels, at the site level or through individual employee discussions. Honda argues that the non-union model supports ongoing competitiveness and continuous improvement, while labor advocates say a union can provide a formal mechanism for collective bargaining and workplace protections.
Summary
In short, Honda’s plants in Ohio are not unionized as of 2026. Although the UAW has pursued organizing campaigns at these sites, no union contract currently exists. The facilities continue to operate under a non-union framework, with ongoing labor-relations discussions between workers and management as part of the company’s broader approach to workforce relations.
