Etymology
Etymology Information

'union-buster' is a compound of 'union' + 'buster' in modern English; 'union' from Latin 'unio' via Old French, and 'buster' from the agent form of 'bust' meaning 'one who breaks'.

Historical Evolution

'union' comes from Latin 'unio' > Old French 'union' > Middle English 'unioun'; 'bust' is a colloquial 19th-century English variant of 'burst', and the agentive suffix '-er' produced 'buster'; the compound 'union-buster' appears in English in the 20th century in labor contexts.

Meaning Changes

Initially 'buster' simply meant 'one who breaks' (literal breaking); over time in the labor context 'union-buster' came to mean specifically a person or agent who attempts to prevent or destroy labor unions.
