I'd wait to see what happens and assume there will be somewhat acceptable re-booking (if necessary at all).
In the event of the worst, do you have travel insurance which covers missed connections for the flights to Maui? Covers missed hotel nights for flight delay?
Strikes me as an unreasonable sum to put down to to slug it in Y when there isn't any definitive knowledge of whether a strike will happen; there are of seats on other (OW and non-alliance) carriers to get you to your destination should the worst happen.
