It's not exactly unheard of. One feature that makes unions in the United States different from other countries is that they tend to have a more adversarial relationship with employers and the government. Sectoral bargaining is very rare, if it exists at all. Union laws are a patchwork of left- and right-wing administrations' attempts to undermine each other. American culture, in particular the prominence of Manichaean narratives, may play a role in making different groups see each other as "evil" and willing to do underhanded things, whether it's the UFCW planting an ABC news story about Food Lion or Amazon ignoring labor laws to fire unionizing workers. The teacher's union and police union serve as bogeymen for one or the other political party. Advocating compromise is often met with scorn.
