IPA: /ˌæn.tiˈstraɪk/
KK: /æntiˈstraɪk/
Describing something that is against or opposed to a work stoppage or industrial action by workers.
The antistrike policy was implemented to discourage workers from participating in labor protests.
Antistrike is formed from "anti-" (meaning against) and "strike" (from Old English "strican", meaning to touch or hit). The word refers to actions taken against a strike, typically in a labor context.
Think of 'against' ('anti-') something that is 'hit' or 'touched' ('strike') — that's why antistrike means actions taken against a strike.
