Well, many do not work at all, so this should not be a problem.
"A new 30-second spot on Barack Obama's Web site is urging voters to "talk to your boss" or professor and then take the day off from work or school to volunteer for his campaign on Election Day.
The "Take the Day" campaign suggests voters sign up to go to battleground states or work in phone banks closer to home on Nov. 4, when they would normally be at work or in class.
"We can't win this election unless every Obama supporter gets out and votes on November 4th. To do that, we need a massive team of volunteers helping us. Can you take next Tuesday off from work, join the final push, and make sure that everyone who supports Barack turns out to vote?" asks the Web page hosting the ad.
On the trail, Obama has been encouraging voters to go to the polls for early voting, and reports from several states are that Democrats are going into the voting booths in larger numbers than Republicans.
John McCain's campaign, though, scolded Obama for encouraging voters to skip work on his behalf.
"Apparently Barack Obama believes that you can't 'make history' by doing your job, or going to school, or caring for your kids. Apparently Barack Obama thinks the only way Americans can make history is by voting, and working, for Barack Obama," McCain spokesman Michael Goldfarb said in a statement to FOXNews.com. "It's the arrogance of a man who believes Americans either support his candidacy or cling bitterly to guns and religion out of fear and xenophobia."
