IPA: /ˈstraɪkˌbreɪkər/
KK: /straɪkˌbreɪkər/
A person who is employed to take the place of workers who are on strike, often to keep a business running during the strike.
The company hired strikebreakers to continue operations while the workers protested for better wages.
Strikebreaker → It is formed from "strike" (from Old English *strican*, meaning to hit or strike) and "breaker" (from Old English *brecan*, meaning to break). A strikebreaker is someone who breaks a strike, typically by working during a labor dispute.
Think of someone who 'hits' ('strike') against the action of 'breaking' ('breaker') a strike — that's why a strikebreaker is someone who works when others are on strike.
