That's not actually possible in the sense that declaring a day a holiday doesn't actually prevent employers from giving people shifts. If anything, restaurants and stores actually retain more staff during holidays. The only people a holiday would affect would be people working high end jobs that probably wouldn't have issues voting anyways. Vote by mail and extended voting hours are much more effective solutions for people who otherwise couldn't find the time to vote.
