What does antiunion mean?
Antiunion is an adjective describing opposition to labor unions — whether to their existence, their activities, or their influence over workplaces and policy. It is most commonly applied to employers who resist organizing efforts, to legislation that restricts collective bargaining, and to public figures or movements perceived as hostile to organized labor. The word is especially prevalent in American English, where debates over unionization have long been politically charged, and it appears frequently in journalism, labor law, and political commentary. Because unions are often seen as champions of workers' rights, labeling something antiunion frequently carries a critical or pejorative connotation, though supporters of such positions may frame them instead as defending individual freedom or business flexibility. Writers may use either the closed form 'antiunion' or the hyphenated 'anti-union,' with the latter being somewhat more common today. Understanding the term requires recognizing its rootedness in the broader vocabulary of labor relations, alongside terms like pro-union and union-busting.

Born in the battles between American industry and organized labor, 'antiunion' is less a neutral label than a charge — one side's 'antiunion' is another's 'defending workplace freedom.'

Etymology of antiunion
The word combines the prefix 'anti-,' from Greek 'anti' meaning against or opposite, with 'union,' which derives ultimately from the Latin 'unus' (one) via Late Latin 'unio' (oneness, unity). 'Union' entered English in the 15th–16th century both in the general sense of the act of uniting and in specific senses such as the political union of states. The compound 'antiunion' arose in English, particularly in the United States, during the era of industrialization and labor conflict, when opposition to trade unions became a distinct and widely discussed position.
How antiunion is actually used
Primarily used in American English, especially in political, legal, and labor-relations contexts. The term carries strong connotations and is often evaluative rather than neutral — describing someone or something as antiunion typically implies criticism from pro-labor perspectives. Both 'antiunion' and the hyphenated 'anti-union' are accepted spellings, though the hyphenated form is generally more frequent in contemporary usage.
Easily confused with antiunion
