"Wert on strike" is a somewhat obscure phrase that refers to someone who was on strike in the past tense. The word "wert" is a contraction of "were" and "not," and is spelled phonetically as /wɜːrt/. It is an archaic form of English that was commonly used in the past but has since fallen out of use. The phrase itself is not commonly used in modern language but can still be seen occasionally in historical texts or when discussing labor strikes.
