Usage notes change

Most of the time the past participle of “strike” is “struck.” The exceptions are that you can be stricken with guilt, a misfortune, a wound or a disease; and a passage in a document can be stricken out. The rest of the time, stick with “struck.” This rule does not seem to be authoritative. The past participle is stricken.

When dealing with the verb "to strike" in a labour union context, the use of the past participle "struck" sounds awkward at best, and is confusing. If you write "the union struck three times since the 1970s" the reader is left to wonder "struck what?- a deal? or something else?". In such situations the use of one of the following locutions is most often used: "went on strike", "took strike action" to express the simple past.
