You're A Nervous First-Time Poll Worker: A Guide. . .
Thank you for your service! First things first, the AM is usually chaos: locked doors, late coordinators, no police w/ the equipment you need. These problems normally work themselves out, but if not, call the BOE. Then. . .
Introduce yourself to the coordinator and tell them you're new. They'll probably pair you with a veteran, and regardless of what you were assigned, you could end up working any job (except translator lol). A word of warning. . . .
BMD and scanner inspector are (often) the least work, but that also means they're sooooooo boring. In NYC you'll be there for about 17 hours and IMHO it helps to be busy (checking in voters). But no matter the job. . .
Follow your manual, which tells you everything to know about opening, closing, and potential problems. Throughout the day, keep it beside you & don't be embarrassed about referencing it. It's better to be slow than wrong. AND NO MATTER WHAT. . .
Keep track of EVERYTHING, even the plastic wrapping for the ballots. After rushes, make sure you've accounted for provisional ballots, voter registrations, court orders, etc., which will make closing much easier. And speaking of. . .
You can't leave until every ballot is accounted for and the site is fully closed down, so help your fellow PWs. Also, take a photo of the form that the coordinator signs at the end of the night (in case you don't get paid). And don't forget. . .
No matter how efficient / friendly you are, some voters will be rude. That's between them and God. Don't let them rush or rattle you, remember to bring snacks and your own masks, and good luck!
