In Japan, enterprise unionism is the practice of having a union represent the workers in a single company, rather than across an entire industry or region. This type of unionism is unique to Japan and has been a key component of the country's post-World War II economic success. By working closely with management, enterprise unions have been able to negotiate better wages and working conditions for their members while also promoting labor-management cooperation and stability within individual companies.
