Most elections are on the same day every cycle. Schedule your visit like an adult. People schedule all sorts of shit. Most grown folks can do it. Not that hard.
There will be other elections. If you miss one it will swing back around in the next 2-6 years. It's not a big deal. Only children and the very elderly need that kind of help. Or people out of the country.
Then don't vote. Simple as that.
I believe in most places an employer is legally required to allow employees sufficient time off to vote.
