Yes, during a low-turnout primary they are bored; and should bring reading material or knitting... but during a high-turnout presidential election every precinct needs far more people than they already have.
Please get in touch with your county board of elections now and get the few hours of training needed by the county.
Even better, print out and learn the guidance and regulations that are on the Virginia State Board of Elections website. Study the process so you can help.
If you know a second language, or American Sign Language, your skills may come in exceptionally handy on election day. If you are not afraid of computers you are likely to be the most experienced technician on site that day (something that personally scares me).
Most volunteers are retirees, and I have nothing against older people, but the older you are the more set in your ways you are and the less quick on your feet. Election rules change (Help America Vote Act) and some of the volunteers have been doing this for decades, and have not adapted to the new rules. So my appeal is especially to young citizens to volunteer and help out.
Most voters have not bothered to learn the rules, in a busy precinct, it helps if someone can go through the line before they get to the desk where they give their name, address, and some form of ID; explaining to them that they will have to do that and asking them to check while still in line if they have all their stuff ready. Yes, you can vote without ID - but it slows the process down, and you must be prepared to affirm your identify in front of the official in charge of that precinct (usually the one non-volunteer in the group).
Sometimes the parties have election watchers sitting at or behind the official workers, reviewing and sometimes challenging voters. I find this offensive, but it's the law; and it takes more officials to handle that when it happens.
Warning: it is a long day. You have to be there to open the polls, and can't leave until they are closed and the books are closed for that precinct. If everything goes smoothly, that means 55-90 minutes after polls close. If there was a huge line at closing time, everyone already in line at closing still gets to vote; and if there are errors they must be reconciled while all workers are still present. We did not get released from duty at Mullen precinct in 2006 until a little after 10pm. Pay is tiny. Voters are sometimes rude, offensive, and belligerent. Others are really nice and know what to do. Your fellow election workers may be brilliant, or clueless; they may disagree with you politically, or be fellow activists you know. It is a trying time.
It is worth it. You will learn a lot about the election system, about why things are done the way they are. Every voter should work the polls at least once. Please volunteer with your county.
