They may complain about the next date chosen, and will need to be consulted. The Sun God will not be happy if the wrong date is chosen....
They may and they may not. We can cross that bridge when we get there. For now, Jews are a substantial population in some ridings and violating their constitutionally protected religious rights by disenfranchising them unless they ignore a religious tenet (that violates no one else's rights or freedoms and breaks no laws) is a bad idea.
If you want my actual opinion about THIS instance and what should be done, I think they should just be directed to vote at the advanced polls. Election DAY is not the only time you can vote. The whole reason they have advanced polls is for situations like this.
